Thanks!  The (LONGEST) casts look unnecessary, as
hex_string_custom already takes LONGEST.

This needs a ChangeLog entry.  See
<http://sourceware.org/gdb/wiki/ContributionChecklist>.  Could
you send one?

In order to backport to the 7.6 branch, we'll need a bugzilla entry
filed, reporting the bug.  Could you do that?  That will be used
to record the bug fix in <http://sourceware.org/gdb/wiki/GDB_7.6_Release>.
