bug#24848: [sh-script] How to save "Local rules set" result from sh-learn-buffer-indent?

[<richard.wiseman@bt.com>]

Thanks Noam.  I'm not sure I've got any way to test this patch, though...  I don't seem to have an smie.el file anywhere.  I've installed the emacs24-el package expecting that to contain it but it doesn't -- at least, I've searched my entire hard drive for it (using sudo, just in case) and it wasn't found.

Okay, the patch below fixes the loading for me.  I also added a mention
of `smie-config-guess' in `sh-learn-buffer-indent's docstring so that it
should be possible to figure how to save config rules by reading
docstrings rather than hunting in the source code.
