[PATCH 0/1] emacs: don't show duplicate keys in help.

[Mark Walters]

Previously notmuch-help would show two entries for keys in a parent
keymap that were over-ridden in the local keymap.  This keeps track of
which keys have been seen and thus avoids these spurious duplicate
entries.

Currently only pick does this but I think we might easily have the
problem elsewhere in the future.

Since most of the diff is indentation I include a word-diff below
(which is why there is a cover letter and single patch).


Best wishes

Mark
