[neomutt-devel] Refactoring's cosmetics 💄

[Guyzmo]

About refactoring, there's actually two discussions, one being more
focused on cosmetics (tabs, comments, C flavour), but that's what makes
it more or less fun to code for mutt. The other is more about the
refactoring of underlying libraries, but let's push that to Fork
discussion.

* Cosmetics
 * [C flavour]
   * flatcap: mutt supports C99 (which isn't too bad), but not C11 there are
     probably more people out there with C99 compilers than with C11 compilers
   * clang ≥ 3.0 and GCC ≥ 4.9 have full C11 support, and both are more
     than 5 years old.
 * [Spaces vs Tabs] killall TABs?
 * add comments to all return codes

Cheers,
