For me personally, if I knew a simple patch integrated cleanly and
passed on at least one buildbot -- when it wasn't a platform-specific
fix -- then I could easily push a "Commit" button and be done with it
(although this assumes single branch committing; doing this across
branches makes all of this difficult unless we finally resolve our
Misc/NEWS conflict issues so that in some instances it can be
automated). Instead I have to wait until I have a clone I can push from,
download a patch, apply it, run the unit tests myself, do the commit,
and then repeat a subset of that to whatever branches make sense. It's a
lot of work for which some things could be automated.

The Misc/NEWS issue could be easily solved. Mercurial allow to specify a custom merge tool for specific file. And I already succesfully wrote dedicated merge tools for file with similar issue.

I've already discussed that with various people Larry, Nick, etc. And what is needed now is someone actually doing the work.

Once you have such tool, you can have automatic pull request merge/rebasing through a web ui. -However-, You can only do that if you actually own the said interface. Because propriétary plateform are not going to let your run arbitrary code on their machine.
