[PATCH 0/4] Allow oldest-first view in tree view

[Mark Walters <markwalters1009@gmail.com>]

This series allows the user to toggle the sort order in tree view and,
in particular, allows oldest first view.

Note that in all cases messages within a thread are displayed in
thread order: the option only affects the order when multiple threads
are viewed. If you only use tree view for single threads then nothing
will change.

Since tree view uses the notmuch-show command line as a backend this
means we need to add a --sort option tonotmuch show. This is the first
patch.

The second patch implements the toggle sort order option bound to 'o'
(so the same as the corresponding command in search view).

These third and fourth patches are more optional: they make notmuch
tree view inherit the notmuch search order when called via Z
(notmuch-tree-from-search-current-query), and use the default
notmuch-search sort order (notmuch-search-oldest-first) when called
interactively. The third patch does the code change and the fourth the
test update.

I think these last two patches make sense for consistency but I have
no strong feelings otherwise.

Best wishes

Mark
