[Libguestfs] [PATCH] fish: Fix glob command (RHBZ#635969).

[Richard W.M. Jones]

Note this bug was very confusing because glob works when you use the
-x (trace) option, so when you try to trace the commands being run
the bug "disappears".

Subject: [PATCH] fish: Fix glob command (RHBZ#635969).

This is a fix for the glob command in guestfish which was inadvertently
broken in commit c359347dd42c9f5b875630537ee3641264826b89.

This also appears to fix:
