Patching bad commits

[Michael Witten <mfwitten@gmail.com>]

Sometimes bisecting is less than useful because a number of commits
fail to build.

How about implementing something SIMILAR to "git notes" (perhaps
even using "git notes") to store and apply patches for such bad
commits?

For instance, bisecting could transparently apply any patches that
are necessary to make a bad commit actually buildable; such patches
could be distributed as usual for the benefit of others.

I'm thinking that a "patch note" could have 2 forms:

    * A plain patch file (or maybe a git tree of patches).

    * A reference to another commit that should be checked
      out instead.

Is this a worthwhile idea?

Sincerely,
Michael Witten
