[PATCH v3 2/2] search: Support automatic tag exclusions

[Pieter Praet]

Nice feature!  I won't be using it myself, but I can imagine it being
*very* useful for those who still feel the need to "delete" email :).


Nitpicking:

- All other config-related functions and args include the section title
  in their name [1], so for the sake of consistency, we might want to
  mirror that.  Also, the "auto"matic part is pretty much a given.

  So I'd like to suggest replacing all occurences of "auto_exclude_tags"
  with "search_exclude_tags" (and simply "exclude_tags" in the args to
  `_config_get_list' and `_config_set_list', of course).

  Unfortunately, this would also partially invalidate your recent NEWS
  submission [2].

- If the 'search.exclude_tags' option is missing from the config file,
  its value is automatically set to "deleted;spam;", which probably isn't
  a sane default.  Luckily, you've already provided the solution [3].

- To make new users aware of the config option's existence, we should
  prompt them to configure it during setup.

Patches follow.


Peace
