doc: lei-overview: favor Maildir for mutt examples

mboxes are generally horrible for interactive read-write use due
to locking.  Describe our parallel behavior with mutt, since
writing mail can take a long while and being able to read
results as they're written is nice.

We'll also use a gzipped mboxrd for the import example, since
we can decompress gzipped mboxrds automatically, now.
