OK, so the problem seems to be here:

      # Ignore :descriptions at the ends of lopts for matching this;
      # they aren't in the patterns.

I'm still not quite following this, but I think that stuff is supposed
to distinguish descriptions of options from descriptions of the
arguments those options accept.  If that doesn't happen correctly, the
options having descriptions containing an "=" later reach this ...

      # Descriptions with `=': mandatory argument.
      # Basically the same as the foregoing.
      # TODO: could they be combined?

      if (( $#tmpo )); then

and in that block they get transformed from e.g -a:description: to
-a=[description] which is wrong.
