107fe7c081 less: improve search when data is not supplied fast enough by stdin - 
now will try reading for 1-2 seconds before declaring that there is no match.
This fixes a very common annoyance with long manpages.

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.
 2006-12-21 00:22:03 +00:00
Denis Vlasenko
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).

01e: rewrite special-key handling to be smaller.
01f: changing the format saves 4 bytes (alot of places would benefit from this)

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.
