Now, when address related outputs are in a separate command, it makes
no sense to combine multiple --output options in search command line.
Using switch statement to handle different outputs is more readable
than a series of if statements.
This moves address-related functionality from search command to the
new address command. The implementation shares almost all code and
some command line options.
Options --offset and --limit were intentionally not included in the
address command, because they refer to messages numbers, which users
do not see in the output. This could confuse users because, for
example, they could see more addresses in the output that what was
specified with --limit. This functionality can be correctly
reimplemented for address subcommand later.
Also useless values of --exclude flag were not included in the address
command.
This was inspired by a patch from Jani Nikula.
The new outputs allow printing senders, recipients or both of matching
messages. To print both, the user can use --output=sender and
--output=recipients simultaneously.
Currently, the same address can appear multiple times in the output.
The next commit will change this. For this reason, tests are
introduced there.
We use mailbox_t rather than InternetAddressMailbox because we will
need to extend it in a following commit.
This code is based on a patch from Jani Nikula.
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.
