Christoph Lohmann b0bddc694a Add a hack to handle unknown chars in fontconfig.
The unicode long is added to the cache. So when fontconfig does fall back to
the default font (where there is no easy way to find this out from the
pattern) it isn't reloaded.

Johannes Postma 487bbb24d0 Update kdch1 definition to three octal digits.
ncurses wasn't able to detect the delete-character key as KEY_DC.  This
patch fixes that.

kdch1 was defined as "\0177", but terminfo(5) states:
	... characters may be given as three octal digits after a \.

The delete-character key is correctly defined in config.def.h.

Ivan Delalande 1b514048b2 Let curses do the dirty work for flash
Use the terminfo delay syntax ($<x>) in our flash capability to avoid
hardcoding a fixed delay in redraw() when called from tsetmode() with
DECSCNM.
We need to turn on the npc capability so that delays are made with
xon/xoff instead of padding characters.

Rian Hunter aba6c292af Correct shift amount on MODE_INSERT in tputc()
When MODE_INSERT is set we'd shift characters on the same
line forward before inserting our character in tputc().
This did not account for wide characters where width != 1.
This patch makes it so we shift the correct amount.

Rian Hunter 4d14d97547 Fix crash due to wide characters
In tputc(), when a character wasn't large enough to fit
on the current line, we would call tnewline() to place it on
the next line. Unfortunately, we weren't resetting our glyph
pointer and this caused memory corruption when a
wide character (width == 2) was being written. This patch
resets our glyph pointer after calls to tnewline().

Ivan Delalande 708b697ed7 Fix crash due to invalid timespec given to pselect
If blinktimeout is set to a value greater than 1000, pselect will
receive a timeout argument with tv_nsec greater than 1E9 (1 sec), and
fail, making st crash. This patch just ensures that the timespec
structure is correctly filled with a value properly decomposed between
tv_sec and tv_nsec.

Reported by JasonWoof on IRC. Thanks!

Ivan Delalande 09f5d98251 Trim trailing whitespaces in every selection case
Trailing whitespaces are trimmed when copying from normal selection and
rectangular selection on lines that have their last character included
or on the left of the selection. It leads to inconsistent behaviors when
copying the exact same text from the left and right window in
applications with vertical splits.
This patch solves this issue by always trimming the selection.

sin 4418939dd9 Call _exit() instead of exit() if exec*() fails
exit() will also unwind the atexit() functions.  This is bad
because if exec*() fails the process is in an inconsistent state.

Eric Pruitt bafbba56cd Check for presence of SHELL environment variable
- POSIX states the SHELL environment variable "... shall represent a
  pathname of the user's preferred command language interpreter." As
  such, st should check for its presence when deciding what shell to
  use; just as HOME can be defined to override one's passwd-defined home
  directory, a user should also be able to override their passwd-defined
  shell using the SHELL environment variable.

CustaiCo 86633ada91 patch for bell in st
The XBell() call currently used when a bell is recieved sends a message
to the X server, but if the X server doesn't know how to sound it,
it just gets ignored and I have not been able to find anywhere in x.org's
code a way to configure the action that the server does.

However, if you use XkbBell() then you can have a process listening for
the XkbBellNotifyEvent that is produced and either alert you visually or
play an audio file or whatever you want as your notification. You have
to include one more header file but the function seems to be compiled as
part of Xlib, at least on my installation.

Roberto E. Vargas Caballero dcfe505d3c Use G1 for alternate charset
St has enacs, which must be printed if a program requires to use
the alternate charset (graphic charset), that in st case was to
select charset graphic for G1, but it was not useful
at all because smacs and rmacs were always redefining the value

definition, but st was doing just the inverse.

Roberto E. Vargas Caballero 5afb3862ba Add support for utmp in st
St runs an interactive shell and not a login shell, and it means
that profile is not loaded. The default terminal configuration
in some system is not the correct for st, but since profile is
not loaded there is no way of getting a script configures the
correct values.

St doesn't update the utmp files, this is the job of another
suckless tool, utmp. Utmp also opens a login shell (it is the
logical behaviour when you create a new user record) it is a
good option execute utmp and then get a correct input in
utmp, wtmp and lastlog file, and execute the content of the
profile.

Ben Hendrickson 98a1085d0e Removing wrapping newlines from selection
When getting selected text, lines that were wrapped because of length
ought not include the wrapping newline in the selection.

This comes up, for example, when copying a bash command that is long
enough to wrap from the console and pasting it back into the console.
The extra newline breaks it.

Similiarly, changes behavior when trimming whitespace from the end of a
physical line to only do so if the line does not wrap. Otherwise we are
trimming whitespace from the middle of a logical line, which may change
its meaning.

Ivan Delalande 51466e019a Change the behavior of word snapping on delimiters
This makes any sequence of identical delimiters be considered a single
word in word-snapping mode. This seems more coherent for this mode and

Roberto E. Vargas Caballero 6530025bca Fix portability problem in techo()
ISCONTROL chechks if a value is between 0 and 0x1f or
between 0x80 and 0x9f. Char signess depends of architecture
and compiler, so in some environment the second case is
always false (and wrong), Techo() calls ISCONTROL with a
char variable, whose type cannot be changed because tpuc()
expects a pointer to char, so the solution is to insert a
cast in the call to ISCONTROL.

Roberto E. Vargas Caballero 821a6e00a5 Remove ul capability
This capability indicates that underscore '_' overstrike current
letter under the cursor. It means that you can generate a
underline 'b' using 'b^H_', because it writes a 'b' then backward
one characther and then overstrike '_'. St has not such behaviour,
so it is an error to have this capability.

Roberto E. Vargas Caballero 8de8ae3923 Unset mode when clearing regions
tclearregion() was clearing regions using spaces and the current
attributes of the terminal. It was correct with all the modes excepct
underline, because they didn't affect the space character, but in
the case of underline it was a problem. A easy way of seeing this
problem is writing this in the last line of the terminal:

	tput smul ; echo first; tput rmul; echo second; echo third

Fist was underlined, and second and third were not underlined, but
the spaces at the right of second was underlined becuause in the
previous scrool underline mode was set.

Roberto E. Vargas Caballero 769d481807 Remove difference between fast and slow blinking
One blinking mode is good enough, and two is too much. The best aproach
is emulate the fast blinking with the slow blinking, that it is more
used.
It is removed the flag ATTR_FASTBLINK because it has not a different
meaning of ATTR_BLINK, so it is not needed.

Michael Forney b4dfa18124 Fix disabling of bold and fastblink
According to ECMA-48¹ 8.3.117, an attribute value of 21 is "doubly
underlined", while 22 is "normal colour or normal intensity (neither
bold nor faint)".

Additionally, 25 is "steady (not blinking)", which likely means neither
slow blink nor fast blink.
