Yeah I was thinking about this.

Since as always with a new tool there are some doubts over it's
usefulness. I could easily hook it up to a branch in my own fork of
git and keep that branch rebased on top of pu. I'd need to keep an eye
on it myself and report errors on the list.

If that goes well, at some point someone will ask how I'm detecting
these errors. Then I can point them at this patchset and if enough
people want easy access to it then that may provide an incentive for
this to be merged into git.git.
