Move the brief help text at the bottom of the hello screen to the
notmuch-hello-mode help, and promote '?' as the universal help key
across Notmuch. This unclutters the hello screen, and allows for a
more verbose description in the mode help. Hopefully, this change is
useful for both experienced and new users alike.
While at it, improve the links to Notmuch and hello screen
customization.
Before the change, "s" in notmuch-hello buffer would jump to the
search box. The patch changes the binding to `notmuch-search' which
is consistent with all other notmuch buffers.
This makes `show-trailing-whitespace' happy, i.e. it does not mark the
whole search box line as trailing spaces.
Since the dot is invisible, this change makes no visible difference
for `notmuch-hello'.
Edited-by: Pieter Praet <pieter@praet.org> to fix the tests.
One is quoted printable, the other users 8 bit encoding. The latter
triggers a bug in the python bindings due to missing call to
g_mime_init. The corresponding test is marked broken in this commit.
It is very convenient when C-e (bound to `widget-end-of-line') ignores
trailing spaces inside the search widget. But it only does so if a
widget is not followed by a newline (that is why it works in the saved
search widgets). The patch just adds an invisible space after the
search widget to get the desirable behavior of `widget-end-of-line'.
The extra space is also added to expected results of emacs tests.
