[PATCH] snprintf "%lld" support

[TAKAHASHI Tamotsu <ttakah@xxxxxxxxxxxxxxxxx>]

It seems easy and straightforward
to support %ll in snprintf.c.

Now config.h determines OFF_T_FMT,
snprintf should support %ll.

Otherwise, index_format="%c" displays
"dK" for medium-sized messages.

If you decide not to support %ll,
you should avoid %ll in config.h
or mutt_pretty_size.
