this was overlooked when adding hidden line support. if the lines are
removed, Irssi has to update the startline. It does that by "scrolling"
the lines to the proper place. The scroll function was adjusted to
calculate 0 for hidden lines, thus it would miss them.
This adds a i_wcwidth() function that replaces mk_wcwidth(), and a
'wcwidth_implementation' setting to pick which one it wraps.
Values:
- old: uses our local mk_wcwidth() which implements unicode 5.0
- system: uses the libc-provided wcwidth(), which may be better or worse
than ours depending on how up to date the system is.
- auto: tests the system one against two characters that became
fullwidth in unicode 5.2 and 9.0 respectively. If either of them pass,
pick the system implementation, otherwise pick ours.
It defaults to auto.
mk_wcwidth() is still preferable in some cases, since the way it uses
ranges for fullwidth characters means most CJK blocks are covered even
if their characters didn't exist back then.
The "system" implementation is also wrapped to never return -1, but to
assume those unknown characters use one cell. Quoting the code:
/* Treat all unknown characters as taking one cell. This is
* the reason mk_wcwidth and other outdated implementations
* mostly worked with newer unicode, while glibc's wcwidth
* needs updating to recognize new characters.
*
* Instead of relying on that, we keep the behavior of assuming
* one cell even for glibc's implementation, which is still
* highly accurate and less of a headache overall.
*/

* may be buggy
This commit adds support for sideways splits into Irssi. To that regard,
there are a number of new commands available
the "R" commands:
/window new rsplit - make a new sideways split
/window rshow - show an existing window to the right
/window rgrow/rshrink/rsize/rbalance
- manipulate the size of your sideways split windows
the "D" commands:
/window dup/ddown/dleft/dright
- navigate the windows directionally, as an alternative to
/window up/down that you can bind to some key
/window move dleft/dright - the same for moving
Enjoy!
256 colour patch is cleaned up and the remaining cases are made work,
this includes especially Theme support, which was not implemented
before. Changes not related to colours were reverted again, making a
review of the two patches against master easier to follow.
As a byproduct of the Hex-colour code parser, the 24bit colours are
also implemented. Actually using them in the terminal is guarded by a
compile time switch (as well as a run time switch), as it breaks the
existing colour protocol and requires additional storage.
To make a seamless usage, down-conversion is provided for 8 and 16
colours.
Diverging from Tom's approach, the colour protocol is reverted back to
the original one. Unfortunately, the changes required in the Theme
engine will break the API.

This patch implements some 256 colour support for Irssi up from the
previous 16 colours. Initial parsing of the %x/%X format codes is
implemented and the parser accounts in advances the char* for
that.
The colour attributes are widened from 4 to 8 bit. The colour protocol
is changed to a new format. Some pointers to remaining work are
written in the comment in textbuffer.h.
Note that Irssi already does support requesting 256 colours from the
terminal in the original source code, so this part did not have to be
touched.
position where to draw a new line and if the view is at the bottom of the
textbuffer, but the same information can be computed more easily by other
means.

the eighth bit of the color. The formats KBGCRMYW and the mirc colors are now
mapped to colors 8-15. fe-text translates colors 8-15 to bold/blink+0-7 if the
terminal supports only 8 colors.
