[PATCH v3 7/7] emacs: help: base-keymap-test-help

[Mark Walters <markwalters1009@gmail.com>]

Add an argument to notmuch-help for the mode to display help for.
This aids testing of the base-keymap case in remapping in emacs help.

It is only intended for testing, ie not for master (but it does no harm)
