_main_complete localizes `match` already.  So if we don't localize all
of them in the same place then we're risking inconsistency, no matter
what.

Anyone know of a good reason to not just localize _all_ of the =~
non-BASH_REMATCH variables in _main_complete so that they're always
isolated to the completion-system, if =~ or -regex-match or -pcre-match
is used within the completion system?
