[erlang-patches] patch: Allow a user_defined function to wrap mnesia_schema:merge_schema()

I thought I'd follow your advice, but am running into

:~/src/otp/git/mine/mnesia_merge/otp$ git push origin
schema_merge
error: Cannot access URL http://github.com/uwiger/otp.git/, return code 22
fatal: git-http-push failed

That's not an error I've seen before, and I've spent 30 minutes
trying to hunt down the cause.

It's a trivial fix, and the important test that needs to be done
is running the mnesia test suite, which I don't have access to.
Perhaps you could just do it at your end, this one time? :)

BR,
Ulf W
