Looks good, since another instance of "_hg_cmd debugcomplete" already has HGPLAINEXCEPT=alias.

JFYI, I've tried this with my "crecord = !$HG commit --interactive --config ui.interface=curses $@" alias and since `hg debugcomplete --options crecord` only lists global options, it still couldn't complete --amend or --secret...
