- 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.
Howdy,
Bug #1006 reports that
ln -s /tmp/foo .
does not work correctly. In fact, it appears that any instantiation of
ln -s FILE... DIRECTORY
does not work. The following patch adds support for this form, which
then fixes the particular instance noted in the bug report.
In the process, I needed the basename function. This appears in the
string.h provided by glibc, but not uC-libc. So I wrote my own to go in
utility.c, called get_last_path_component. I also modified the basename
utility to use this function.
At some point it might be desirous to use the basename from the library
if it exists, and otherwise compile our own. But I don't know how to do
this.

GNU tr complains on the following:
$ tr a ''
tr: when not truncating set1, string2 must be non-empty
BusyBox tr does not complain:
$ tr a ''
a
^D
0
It should result in an error, not in some spurious output. The attached
patch generates an error.

However, the case of
grep foo$ file
didn't work, due to a problem with the flags used in regular expression
compilation. The attached patch fixes this problem.

Thanks, Matt, it works great.
GROWBY - 1, then it writes the null character just after the buffer. Yipe.
Fix thanks to Matt Kraai <kraai@alumni.carnegiemellon.edu> Thanks Matt!
