I expected there to be a shell caller here or in patch 2/2, but there
isn't. Is this for topgit?

Yes, I had topgit in mind when adding that option.  Assuming it will
make it into git.git, I won't use it for some time though to not depend
on bleeding edge for topgit, though.

It wasn't intentionally that I sent the two patches in a series.

Best regards
Uwe

Hello,

there is no caller for --stop-at-non-option in git-core itself.  This is
mainly targeted for topgit and its successor I currently code up.

Since the last post I only updated it because the old patch resulted in
two merge conflicts (git-rev-parse learned "--sq-quote" and parse_options
got a new argument "prefix")
