I can't see any evidence that the value of _comp_tags is actually used
except for being assigned to _lastcomp[tags] right at the end of
_main_complete, which suggests it shouldn't be reset.  _lastcomp[tags]
is only used in _next_tags, where it's used (via _next_tags_not) for
excluding things.  This suggests that its length growing has a
negligible effect.  On the other hand, it might nonetheless benefit from
being a "typeset -Ua" and being manipulated as an array---it's (limited)
mode of use means that won't stop anything working.
