Should we simply catch > such combinations and error out (which may be a bit more complicated > than this patch, or maybe not)? I'd cross that bridge when we see what the option is. But my gut is that rules would be: - apply all non-conflicting relevant options. So: --exclude=foo/* --decorate-refs --decorate-reflog --remotes would presumably decorate both ref tips _and_ reflogs for all remotes (except ones in refs/remotes/foo/*) - for ones that are directly related and override each other, use the usual last-one-wins rule. So: --decorate-reflog --no-decorate-reflog --remotes would countermand the original --decorate-reflog. - for ones that really have complex interactions, notice and complain in handle_refs(). That just seems to me like it follows our usual option parsing procedure. The only difference here is that process and reset some subset of the flags when we hit a special marker option ("--remotes" in these examples) instead of doing it at the end. -Peff
