screen update. Makes "man bash", [enter], [/],
<enter search pattern>, [enter] more usable - manpage
draws as you enter the pattern! Yay!!
less: fix bug where backspace wasn't actually deleting chars
less: "examine file with empty name" doesn't abort anymore.
libbb: add "all fatal signals" mask.

trylink: explain how to modify link and drastically decrease amount
of padding (unfortunately, needs hand editing ATM).
*: add ALIGN1 / ALIGN2 to global strings and arrays of bytes and shorts

But we do not read entire input anymore up-front.

small fixes. [prev commit also added control char filtering
on input (e.g. regexp input, filename input for 'E' etc)]
|
|
user interaction if stdout is not a tty.
size optimizations
|
|
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.
|
|
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)

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.

things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes... General cleanup pass. What I've
been doing for the last couple days.
And it conflicts! I've removed httpd.c from this checkin due to somebody else
touching that file. It builds for me. I have to catch a bus. (Now you know
why I'm looking forward to Mercurial.)
