Hi,

I've recently begun to use Emacs' interface for mairix(1) for indexing
and searching through my mail, and have noticed two small issues.

The first one is that the main interactive entry points for mairix.el
aren't autoloaded (I'm guessing the present mechanism for autoloading
wasn't available when it was written?). The first patch adds appropriate
';;;###autoload' lines before commands which can serve as such.

The second is that `mairix-search-options' isn't actually used, even
though both the manual and the docstring seem to indicate that it should
be. The second patch modifies `mairix-call-mairix' slightly to add the options
specified.

Note: I haven't completed copyright assignment yet (I need to get a
disclaimer from my university still, might take a while), but I hope
those changes are trivial enough to be accepted without it.
Also, apologies in advance if I should've sent these patches separately
(they seemed trivial enough to be sent together).

Regards, Daniel
