* Fixed basename to support stripping of suffixes. Patch thanks
to xiong jianxin <jxiong@uiuc.edu>
* More doc updates
+ * cp -fa now works as expected for symlinks (it didn't before)
+ * zcat now works (wasn't working since option parsing was broken)

Bugs that need fixing as of Mon May 8 17:22:06 MDT 2000
- - zcat option parsing broke (maybe replace zcat binary with a shell script?)
- - cp -fa doesn't work (-a option parsing probably overrides everything)
- 'grep foo$ file' doesn't work
- 'grep *foo file' segfaults
- ps dirent race bug (need to stat the file before attempting chdir)
