dvtm is too fast in starting up. It will then have a race condition in finding
the right. terminal size.

Ttyread() calls to ttywrite, so if we check for reading before
that for writing in ttywrite we can get a circular call sequence.

ARGUM isn't used and ARGNUMF uses estrtol() that isn't defined anywhere.
Those were probably copied from sbase arg.h.

ttywrite was assuming that if it could not write then it could
read, but this is not necessarily true, there are some situations
where you cannot read or write. The correct behaviour is to detect
if you can read or/and write.

If we want to show a custom selected cursor color, we must not set the
revert attribute to the drawn glyph.

»IBeam« is now »Bar« because it's named like that in the source code.

This adds an awareness commit for the big key array too.

Before the fix the cursor wouldn't obey if it's in a selection. If it is
inside it will now change to the reverse. This patch also adds that the
defaultcs will be reversed for the manually drawn cursors.

Before this patch, when pasting over BUFSIZE (8192 bytes here), st would
do the following:

    \e[200~...8192 bytes...\e[201~\e[200~...remaining bytes...\e[201~

With this patch, the start marker is only sent when the offset is 0 (at
the beginning of selnotify) and the end marker is only sent when the
remaining bytes to read are 0 (at the end).

For short pastes, both conditions are true in the same iteration.

For long pastes, it removes the extra markers in the middle, keeping the
intended wrapping:

    \e[200~...8192 bytes......remaining bytes...\e[201~

gcc would warn about an unused result. We know it is 0 and dup()
can't fail in these circumstances, as we closed fd0 previously.
Using dup2() to do the same saves one line and shuts gcc up, bringing
us a clean build back.

The antialiasing was false due to circumstances that do not exist anymore. We
need antialiasing on big screens with big fonts. Autohinting too.

When a line has no any character linelen is 0, so last = &term.line[y][MIN(lastx, linelen-1)]
generated a pointer to the end of the previous line. The best thing we can do in this case
is to add a newline, because we don't have a glyph to print (and consult its state of
wrapping).

This configuration is basically 38400 8N1, without echo and
in raw mode. Kernel will not process any of the characters
sent by the user.

For completeness and documentation add all C1 control codes.

wcwidth() returns -1 for all the non visible characters, but it doesn't
necessarilly mean that they are incorrect. It only means that they are not
printable.

The current acsc entry, copied from xterm was not exposing capability to
display arrows.

A little fix in xwrite().

Subject: [PATCH] Fix type for write(2) return variable.

The allocated lengh of s fits into an integer so we can safely use
ssize_t here.
