skipping commits via commit-msg contents

sometimes its desirable to commit incomplete work separately, for example a struct change thats intended to get compiler to report where changes are needed.

if git bisect were to recognize --skip-bisect in the subject line (or in commit-message somewhere, say top or bottom), then bisection could proceed silently past such commits.

This would also allow rebasing a patchset to markup crappy commits which need further work.

worth having ?
