[notmuch] [PATCH 1/2] add functions to toggle the nearest backwards button of a given type

[Alexander Botero-Lowry]

It was noted that though local expansion was nice, it was also pretty
nice to have an easy way to just open the headers without moving to the
header button. So this exposes a number of symbols which search backwards
in the buffer for the nearest button of the desire type and push it
