Which, by the way, is the main reason I use brace expansion. Type "mv"
and then fill in a file name using tab completion, then insert or
delete something by editing it to have braces and a comma:

mv some-long-file-name-blah-blah-blah
mv some-{long-,}file-name-blah-blah-blah

Et voila! Remove one word from a tab-completed file name. There's no
way that a generic glob expansion tool can do everything that bash
does, and I doubt anyone expects it.
