Fix some problems with indentation (controlled by markup) and
whitespace.
- notmuch.1: reformat
Use .SS macro to make "notmuch setup" a subsection. Introduce another
subsection for the remaining commands.
- notmuch-config.1: reformat
Put all the syntax in the synopsis. Supposedly this is the the UNIX way.
- notmuch-reply.1: fix formatting issues.
Give nicer formatting for synopsis.
Insert missing SEE ALSO header.
- notmuch-dump.1: reformat using subsections
These seems more natural, although, as mentioned, it does require
referring back to the synopsis. Or maybe copying parts of the
synopsis
We mostly just cut and paste the command descriptions into individual
files, with a short header added to each one.
The splitting into subdirectories is to support the use of ./man as an
element in MANPATH, e.g. for testing.
