Talked in person at the sprint about this.  We think putting exec in a
separate command makes sense, and adding 'histprocess' or some equivalent
that operates like:

hg histprocess --rev <revset> --command <cmd>

Where each rev is rebased to not have children, has the command executed
on it, then it's children are rebased on to it.  This is better than
histedit in that it allows the command to run on nonlinear revsets.

I'll work on this later.
