would not match blank lines (bug #1064). Followed Matt Kraii's suit on his
1.42 revision of grep. Tested it, works.

a few other ugly places (do_subst_command got a much-needed overhaul). Also
took out BB_FEATURE_SED_PATTERN_SPACE from Config.h[.Hurd] as the 'p' is now a
standard feature (adds almost no bloat).

the -V (version) flag from busybox sed. It is unnecessary because sed is not a
standalone and should therefore be independently reporting a version number.
Moreover, it is extra code that we just don't need.

(\1, \2...\9). This touched a lot of places in this file and I added a new
function 'print_subst_w_backrefs' in order to keep 'do_subst_command' a
little more tidy.
* I tested this good 'n hard, but will always appreciate more testing from
other, willing folks.
- Noticed that the index_of_next_unescaped_slash was subtly wrong so I
changed both the functionality and behavior (it used to skip over the first
char in the string you passed it, assuming it was a leading '/'--this
assumption is no longer made) this necessitated changing the lines that
call this function just slightly.

- add_cmd_str: segv's were being generated if there was a '# comment' line
(and probably other kinds of lines, too) that was not followed by a
semi-colon or whitespace
- parse_edit_cmd: was returning a wrong number (too low) for the index; it
was not accounting for backslashes eaten, for the fact that we start at the
3rd index in the string, or for the fact that we add an extra newline.
- parse_cmd_str: was returning a wrong number (again, too low) for the index
in the case of single-letter commands (p,d). There was some
over-compensation for this in the 'return' stmt at the end which also
needed some help.
- load_cmd_file: was not eating trailing newlines off the line read from the
command file. This had the deleterious effect of printing an extra newlines
after text displayed from edit (i,a,c) commands.

- Obsoleted the trim_str function (#if 0'ed out -- maybedelete later) in
favor of strrspn.
- Obsoleted the strrspn function (#if 0'ed out as well) as soon as I
discovered that it wasn't needed either.
- Fixed a subtle bug in parse_subst_cmd where it would choke with an error if
there was any trailing space after the s/match/replace/ expression.

to accomodate a trailing '\n'ewline that I append to it later one. This is
only necessary for the case of one inserted, appended, or changed line, but
it's still necessary.

substitution command execution from do_sed_command() and put it in it's own
do_subst_command() function.

expression parsing into it's own subroutine.

- adds case-insensitive matching in sed s/// epxressions
- consolodates common regcomp code in grep & sed into bb_regcomp and put in
utility.c
- cleans up a bunch of cruft
|
|
There is some common code used by both sed & grep that should be put into
utility.c as per Mat Kraai's suggestions/patch on the mailing list.
Specifically, a common regex_compile() and a regex_subst() function need to be
made.

Tested under both libc5 and libc6 and all seems well with these fixes.

Added 'gunzip -t'. inittab support _almost_ works (but it isn't
ready for prime time useage yet).

has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
* Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
* Some cosmetic fixes to ls output formatting to make it behave more
like GNU ls.
