Renaming Tim's glob/wordexp -> my_glob/my_wordexp

When testing with --baseline, the C compiler complained because
Tim's glob()/wordexp() conflicted with those of the standard C
headers.  Since this is a standalone test for experimental
purposes, I took the easy approach of renaming his iterators
rather than adding more symbols to the reservedCSymbols list.
