I've decided that all the lines like this:

   (umovestr(tcp, tcp->u_arg[0], sizeof path, path), pathmatch(path))

are just too ugly.

I'm going to refactor things a bit and add a upathmatch() function
that accepts a pointer to a string in user-space.  That will eliminate
all of the comma-operators in those long boolean return expressions.

I'll submit new diffs on Monday.
