I frequently diff against the "master" branch, and would like it to be easier in magit.
Right now, I can do one of these:
y, then scroll to
master, then hit
d d RET.
l l, then scroll to the commit, then
d r RET
d r master RET
maybe other ways
What I'd like is something simpler, where I can hit say
d m and it would show the diff against
master (or even better, against the result of
git merge-base master HEAD). How can I achieve that?
