BTW, after reading the subject of this bug report, I don't believe there
is a place for wordexp at all.  wordexp is no replacement for
Fexpand_file_name, but rather a means of expanding input in the manner
of a shell, which input might include arithmetic expressions, shell
command substitutions, and other expressions valid as shell input.  If
Fexpand_file_name alone will not suffice, TRT is to replicate the
mechanics of file-truename in whole, not cutting corners with these
admittedly tempting functions.
