Hmm? Are you disagreeing with how I described the issue, or saying
there is no issue at all? I'm not sure.

I know the syntax is meant for other importers, which might accept
different options. My point is that the man page doesn't say anything
about that. If a frontend follows the man page and just prints e.g.
"option quiet", git-fast-import will silently ignore it.

If you dislike my suggested fix "'option' SP 'git' SP ...", then how about
'option' SP <program> SP <option> ('=' <argument>)? LF
and saying that for options supported by Git, <program> must be 'git'?
