Feature idea: git rebase --exec $CMD

Hi,

I find the x/exec function in "git rebase -i" very useful, but it may be tedious to edit the commit list to add something like "make test" after each commit.

Can this functionality be exposed from the command line as well? I am thinking to a [-x|--exec <command>] options which accepts a command as an argument, and executes such command after each commit in the list of commits which are going to be rebased, and stops the rebasing if the command returns a non-0 value.

Maybe this -x option should conflict with -i to simplify its "execute the command after each commit" semantics (what if it is combined with -i and 'x/exec' lines?).

I can draft the man page section for it, but I doubt I can work on the code for now, so I wanted to throw the idea here and see if anyone else wants to pick it up.

I read that calling a "make test" command after each commit could be done using "git rev-list" like in http://sethrobertson.github.com/GitPostProduction/gpp.html#post-post-production but a more friendly way to do that from CLI would be great.

Thanks,
   Antonio
