Summary: test_commands regression failure

Initial Comment:
test_commands does not work on IRIX

It assumes the output of "ls /bin/ls" is a line
that starts with a '-'.  On IRIX that file is
a symbolic link, so the first character is an l.
This causes test_getstatus to fail.

>>> import commands
>>> commands.getstatus("/bin/ls")
'lrwxr-xr-x    1 root     sys           13 Feb 23  
1997 /bin/ls -> ../../sbin/ls'
>>> pat = r'''-..x..x..x   # It is executable.
...                   \s+\d+       # It has some 
number of links.
...                   \s+\w+\s+\w+ # It has a user and 
group, which may
...                                #     be named 
anything.
...                   [^/]*        # Skip the date.
...                   /bin/ls      # and end with the 
name of the file.
...                '''
>>> import re
>>> re.match(pat, commands.getstatus("/bin/ls"), 
re.VERBOSE)
>>>

Here's a context diff for a patch.  (I hate how narrow
this entry textbox is.)  Feel free to adjust the '#'s
so they all line up.
