Oh, I did not mean to suggest hiding it as a comment to silently allow
older fast-import slurp such input and produce broken results.

For input that needs such loosened error checking, old fast-import won't
produce correct results _anyway_, so I would agree that making these
things into explicit commands to cause older fast-import to error out
would make a lot more sense.
