Make all parameter descriptions etc. use reStructuredText definition
lists with uniform style and indentation. Remove redundant indentation
from around the lists. Remove blank lines between term lines and
definition blocks. Use four spaces for indentation.
This is almost completely whitespace and paragraph reflow changes.
Changed one tab in doc/man1/notmuch-show.rst to 8 spaces.
Removed one leading tab in doc/man5/notmuch-hooks.rst to make
the SYNOPSIS style consistent with other pages.
The post-new hook might no longer be needed or run very often if
notmuch insert is being used. Therefore a post-insert hook is needed
(arguably pre-insert not so much, so don't add one). Also add the
--no-hooks option to skip hooks.
This is the output from sphinx-quickstart, massaged a bit, along with
our existing man pages converted to rst.
A skeleton notmuch-emacs manual is also included. It is not suitable
for end user use yet.
