When an hook is defined, a side effect was the creation of the
${notmuchIni.database.path}/.notmuch/ directory by home-manager. If
the Xapian database does not exist yet but this .notmuch directory
exists, Notmuch is confused and throws an error when `notmuch new` is
run (while this should create the database the first time).
This commit changes the hooks paths to $XDG_CONFIG_HOME where Notmuch
expects them (see notmuch-config(1)) instead of inside the maildir
database directory.
It also moves the configuration where Notmuch expects it, but the
$NOTMUCH_CONFIG environment variable is kept for backward
compatibility.
The Astroid program can work without this option,
which should be disabled when synchronising emails with muchsync for example.
This reverts commit fa3d1f98e0.
This reverts the commits
- "alot: change msmtp default command"
8e798e4c28
- "astroid: init"
736e340bde
because they include changes that break some configurations and some
options that are misplaced.
