Hi Olivier!

Richard had originally contacted me and I responded to him as follows:

While removing the extra space will help, upon further reflection, I
have a feeling that we (the MH-E team) will have to clean up the
mode-line some. I'm widening the distribution to get some feedback and
suggestions.

For example, I'm looking at the following mode line:

1:%%  XX  {+outbox/select} 60 msgs (15266-15325)   Bot L60    (MH-Folder Show MC

Note how with a lot of messages, the mode-line real estate is chewed up.

Here's another example:

1:%%  XX  {+mhe-index/foo_and_bar__and_baz} no msgs   All L1     (MH-Folder MC-r

So, long folder names will chew up real estate too.

Here are a couple of ideas:

1. Remove the number of messages in the MH-Folder mode line. In the
   example above, the "60 msgs" text is usually redundant and can be
   largely inferred (if there aren't many holes) from the range of
   messages.

2. Remove the number of messages and the range of messages from the mode
   line (for example, "60 msgs (15266-15325)" above) since you can
   easily get that information by looking at the first message and last
   message in the buffer.

3. Remove the /select from the folder name (which shows that we're only
   looking at a part of a folder--see
   mh-partial-folder-mode-line-annotation). Alternatively, setting
   mh-partial-folder-mode-line-annotation to a single character such as
   `-' might enough to show that you'd only looking at a subset of a
   folder.

4. Use a variant of the Gnus newsgroup abbreviation if the folder name
   is longer than a certain threshold. For example, gmane.emacs.devel is
   g.e.devel. Would we use a similar heuristic?

5. Truncate folder names to 20 characters.

If you're an MH-E user, are any of these ideas repugnant to you? Do any
appeal to you? If you're an Emacs/Gnus developer, can you suggest best
practices for the mode line that our users can evaluate?

Thanks!
