Yes, that works nicely.  ;-)

Now here's my other problem: How does git-gui know the underlying
git will accept --redirect-stderr?  Or that it supports any other
recent features we've developed?

Sure I can check the version, but until I know what version of Git
its shipping in I cannot put the check into git-gui.

I was thinking about adding a "git-supported-features" plumbing
command that prints back feature code strings, much as our
network protocol supplies back the few feature codes it supports
("multi-ack", "sideband", etc.).  E.g.:

  $ git supported-features
  redirect-stderr
  ...

That way higher level Porcelain can poll the plumbing to see what
is available, and what isn't.
