I was reminded today that I planned to forward this here:

http://www.debian.org/Bugs/db/62/62339.html

This is a bug report which notes that rc segfaults if you attempt to
match '*' against the null list ("~ () '*'"). unquoted * is ok.

A quick trace shows that p->m is null (from what i can gather, this
means there are no metacharacters in p->w. documentation on the List
structure would be appreciated).

This is the line we crash on:

	if (p->w[i] != '*' || p->m[i] != 1)

I'm a bit wary of just taking a check for non-NULL p->m on here, since
I don't understand what that means (other than the fact that with an
unquoted *, it's a pointer to "\001"). It seems like the function
really ought to be rewritten.
