Since i personally dislike having a separate config for the editor in git/stgit
i locally use this patch.
unfortunately it makes the whole editor searching thing more complex :-(
But i am sure it is possible to rewrite the code to something easier
with some more python knowledge :-/
So it is not meant for direct applying, just for discussion...

TODO: update sample gitconfig?
TODO: do the same for pager?
