[PATCH] Improve documentation on quick syncs

[dtk]

Hi Sebastian,
think I found a typo.

Excerpts from Sebastian Spaeth's message of Wed Apr 13 10:48:51 +0200 2011:
> +# synchronizations.  It only synchronizes a folder if 1) a Maildir
> +# folder has changed, or 2) if an IMAP folder has received new messages
> +# or had messages deleted, ie it not update if only IMAP flags have
s/ie it not update/ie it does not update/

thanks for the patch!
