[PATCH v5] emacs: display tags in notmuch-show with links

[Damien Cassou]

This patch obsoletes:
id:1355216437-21109-1-git-send-email-damien.cassou@gmail.com

[PATCH 1/4] emacs: Add a thread's tags to notmuch-show header-line
[PATCH 2/4] emacs: Make tags in notmuch-show header-line clickable
[PATCH 3/4] emacs: Make all tags in `notmuch-show' clickable
[PATCH 4/4] emacs: Add unit-tests for clickable tags

These patches make clickable all tags that appear in notmuch-show
buffers. Each tag is a link to open a new notmuch-search buffer for
this tag. Additionally, the buffer's header-line now shows the
thread's tags (clickable only if the `header-button' library is loaded
or loadable).

These patches are the first of an upcoming series whose goal is to
integrate notmuch-labeler into notmuch. See the following for more
details: https://github.com/DamienCassou/notmuch-labeler

With respect to v4, I took care of the comments you made:

- integration of Mark Walters' patch to avoid duplicate update of the
  header-line tags
- implementation of Mark Walters' comment on sorting header-line tags

[PATCH 1/4] emacs: Add a thread's tags to notmuch-show header-line

Re: [PATCH 4/4] emacs: Add unit-tests for clickable tags

[Mark Walters]

Hi 

I thought I had checked the test output but I am getting a failure: the
last test in emacs-show is failing (test_begin_subtest "id
buttonization")

I think it is just saying your patch is working and making the tag inbox
in the message line a button.

Best wishes

Mark
