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.

escape seq. code from tr and echo into utility.c. Fix thanks to
Matt Kraai <kraai@alumni.carnegiemellon.edu>.
* This should close Bug #1015. Please test.

utility.c and replaced them with get_line_from_file() from the new grep.c.
Also changed declaration in internal.h and replaced instances of
cstring_lineFromFile() in dc.c and sort.c with get_line_from_file(). Tested
them and they worked fine.
* Fixed segfault caused by "touch -c"
* Fixed segfault caused by "rm -f"
* Fixed segfault caused by "ln -s -s" and similar abuses.
* Fixed segfault caused by "cp -a -a" and similar abuses.
* Implemented "rm -- <foo>"
updated docs accordingly.
-Erik
- Fixed error message when the command is not specified (possibly crash on
libc5 systems!)
- Debugging output removed
- Using fatalError() whenever appropriate

a big "P" Policy violator -- logname was using getlogin(3), which uses
utmp under the hood. We don't need no stinkin' utmp (and if we
are using tinylogin, it is unlikely to be useful trying).
-Erik
* cp/mv now accepts (and ignores) the -f flag, since it always
does force anyway
* tail can now accept -<num> commands (e.g. -10) for better
compatibility with the standard tail command
* added a simple id implementation; doesn't support supp. groups yet
utility.c :: cstring_alloc()
utility.c :: cstring_lineFromFile() /* they're at the bottom */
so that I could read in lines of arbitrary length from FILE*s
(instead of using fgets(huge_ass_buffer,...)).
+ I tested it out on sort, and it seems to be fine.
