Allow setting a policy about what context to choose when starting mu4e
and composing a message. Basically:
When you have defined contexts and you start mu4e it decides which
context to use based on the variable `mu4e-context-policy';
similarly, when you compose a new message, the context is determined
using `mu4e-compose-context-policy'.
These policies can be one of the following:
- a symbol always-ask: unconditionally ask the user what context to pick
The other choices only apply if none of the context matches (i.e., if
none of the contexts' match-functions returns t:
- symbol ask: ask the user
- a symbol pick-first: pick the first context
- nil: don't change the context
Update mu4e-context-switch to not call the enter/leave functions when
'changing' to the current context. However, calling those functions (if
defined) can be force through a prefix arg. Document this.
Make mu4e-context-determine recognize 'policies', i.e. what to do when
no context matches. This part is WIP.
Since the environment (and settings) can change, default to
re-calculating the maildirs when we need them. When you have so many
maildirs that this is slow, you can set mu4e-cache-maildir-list to
t (but be sure to read the docstring).
Make `global-mode-string' local in all buffers where we use it, so we
don't leak the "context" string outside mu4e.
Also add the context string to the compose buffer's modeline.
This fixes#740.
When contexts have been defined, automatically select one at startup --
either the first whose match-function returns non-nil, or simply the
first one.
Document this, too.
Let's not spam the poor sods who own foo.com and bar.com, or home.com
etc. Went through the various examples and changed them to use
example.com or subdomains of example.com where appropriate, even when
the domain or TLD didn't exist (yet!) for completeness.

Define mu4e-context - a structure with settings and enter/leave
functions for contexts, and some functions for switching between
contexts and auto-detecting them.
I'm using this for a rather nasty hack. When I open different bookmarks
in the mu4e-main view I want to set options for them, currently just
tweaking:
* mu4e-headers-show-threads
* mu4e-headers-include-related
* mu4e-headers-skip-duplicates
* mu4e-headers-results-limit
This is because some of my searches are *really* expensive when I
include related threads (huge batches of cron-generated E-Mails), but
some aren't. I couldn't find another way to do this. Using
mu4e-headers-mode-hook doesn't work, because we don't have access to the
search (just a variable showing the last search).
Also maybe we should be passing the actual key chord for the bookmark
here. I don't care since I look up the search string that'll be executed
and go from there, but maybe that interface would make more sense.
But whatever, this works for me, and solves a real use-case.
Right now we have this for showing the status of messages, e.g. whether
it has an attachment etc. But not for the "d", "D" etc. in the leftmost
column of the headers view.
This adds support for that, while bending over backwards to ensure that
anyone who's customized this in the past won't have their customizations
broken, i.e. like `mu4e-headers-trashed-mark` we can set this to a cons
cell of basic/fancy characters, but we also continue to support this
just being a string for existing users.
The next patch in this series adds a couple of non-ASCII characters to
be used for the trash / delete mark.
