these are resulting fixes

2006-12-24less: implement waiting for input using select(). Rather tricky business.Denis Vlasenko
But we do not read entire input anymore up-front.

2006-12-21less: "(null)" is a bit strange. "standard input" is better :)Denis Vlasenko
2006-12-21less: how many different kinds of status line we need, three?!Denis Vlasenko
small fixes. [prev commit also added control char filtering on input (e.g. regexp input, filename input for 'E' etc)]
2006-12-21less: stop dying on bad regexps, quietly pipe data w/oDenis Vlasenko
user interaction if stdout is not a tty. size optimizations
2006-12-21less: total cleanup and bugfix.Denis Vlasenko
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.
2006-12-20less: somewhat buggy applet, but nice. Muchly reducedDenis Vlasenko
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).

01a: svn version 01b: merge past_eof and inp_stdin into flags. 01c: merge match_backwards into flags. 01d: add handling of <HOME> and <END> keys, remove set_tty_raw, use fflush_stdout_and_exit 01e: rewrite special-key handling to be smaller. 01f: changing the format saves 4 bytes (alot of places would benefit from this) text data bss dec hex filename 9034 8 648 9690 25da less.o.01a 9023 8 640 9671 25c7 less.o.01b 9027 8 636 9671 25c7 less.o.01c 9068 8 636 9712 25f0 less.o.01d 8990 8 636 9634 25a2 less.o.01e 8986 8 636 9630 259e less.o.01f

2006-10-03getopt_ulflags -> getopt32.Denis Vlasenko
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.
