[PATCH 0/3] reworked crypto toggle, plus a couple of other toggles

[David Edmondson]

The crypto toggle previously worked using an argument to
`notmuch-show' and various other functions and relied on killing and
re-creating the notmuch-show-mode buffer. Various other
pseudo-buffer-local variables were present based on an ad-hoc scheme.

Replace the ad-hoc scheme with real buffer-local variables and then
update `notmuch-show-refresh-view' to erase and re-paint rather than
kill and re-create. Update the crypto switch accordingly.

Add two other toggles:
    - whether non-matching messages are available,
    - the indentation of message contents.
Both of these default to the current behaviour.

A wart in the first patch is the handling of the
`notmuch-show-process-crypto' default. It is set based on
`notmuch-crypto-process-mime', but the users choice of setting for
that variable may not have been applied at the point where
`notmuch-show-process-crypto' inherits it.

My inclination is to remove `notmuch-crypto-process-mime' altogether
(declared it an obsolete variable) and allow users to set a default
for `notmuch-show-process-crypto' directly, but that is not done in
this patchset while awaiting feedback.

`notmuch-crypto-process-mime' is used only in notmuch-show.el, so the
setting really belongs there with an appropriate name.

David Edmondson (3):
  emacs: Rework crypto switch toggle.
  emacs: Allow `notmuch-show-mode' to display only matching messages.
  emacs: Allow the indentation of content to be toggled.
