The value of the fullname will always match the output of
-file-list-exec-source-files. You use the same function
"source_full_path_of" and pass in the same symtab that
-file-list-exec-source-files uses. In fact, that function reuse's
symtab->fullname if it has already been calculated and is still on the
disk.

I personally think that at best, Eli's originally regex will need to be
used. For instance, I don't believe that GDB should change in order to
get the proper regex in this testcase. I believe that we should use a
regex that matches the current output of GDB. If it is determined that
GDB is broke, it can be fixed in another patch.
