  1.04; sorry, forgot to say so. ]

Globbing doesn't work right:

bash$ ls
abc     abd     bbc     cbc
bash$ echo *[^c]
abc abd bbc cbc
bash$ 

I understand that *[^c] should match any sequence of characters
followed by a single character which is not a c; only abd should have
matched.  The problem is that [^c] is matching the null at the end of
each filename.  The patch below seems to fix this.
