notmuch search does not output header values. However, when browsing
through a large email corpus, it can be time saving to be able to
paginate without running notmuch show for each message/thread.
Add --offset and --limit options to notmuch show. This is inspired from
commit 796b629c3b ("cli: add options --offset and --limit to notmuch
search").
Update man page, shell completion and add a test case to ensure it works
as expected.
