rsync.yo patch

for:

  rsync --one-file-system --delete-excluded --exclude=/bar/ host:/bar/ /foo

where /bar is a mounted filesystem, 

document that ignoring a sender's "other" filesystem does not affect the operation of --delete-excluded at the matching receiver's patch (/foo/bar).

I ran into this under a pile of scripts where the backups first backed up /foo, then /foo/bar, then /foo/baz, and the underlying volume's CoW snapshots were quickly gaining size because /foo was listed in the excludes (first deleted, then re-populated).

The current documentation isn't wrong - just being explicit would help eliminate this as a gotcha.
