Denis Vlasenko
3f3190e34c less: total cleanup and bugfix.
Doesn't die horribly on binary files anymore.
In fact, they _100%_ work now. Control chars
are in reverse video, including DEL and that idiocy of VT-10x,
Meta-ESC [inventor of which should be prohibited from reproducing].
Regex search is fixed also. When you specify search ('/' key),
control chars turn into dots (unhighlighted),
and found occurrences highlighted instead. This is reversible.
Memory management fixed (was leaky as hell) and optimized.
Linewrapping fixed and thoroughly tested.
Max buffer size made configurable.
~ 600 bytes saved.

9a7cef930f less: somewhat buggy applet, but nice. Muchly reduced
xstrdup'ing and memory consumption. Made linewrap saner.
regex matching code was awful - still buggy, but not as
leaky as before. Made buffer size configurable. Killed
several static and on-stack buffers. Hopefully eliminated
staircase effect on Ctrl-C (unable to reproduce).
