the patch

I need to sync a lot of files with non-zero-padded numbered filenames.

I would like them to be transferred in order, to be able to use "partial"
transfers (it takes a lot of time to transfer the whole data).

My concrete need is to rsync duplicity backups. Let's say I have 21 files. For
now, they are transferred in that order :

duplicity-full.20140531T230029Z.vol1.difftar.gpg
duplicity-full.20140531T230029Z.vol10.difftar.gpg
duplicity-full.20140531T230029Z.vol11.difftar.gpg
duplicity-full.20140531T230029Z.vol12.difftar.gpg
duplicity-full.20140531T230029Z.vol13.difftar.gpg
duplicity-full.20140531T230029Z.vol14.difftar.gpg
duplicity-full.20140531T230029Z.vol15.difftar.gpg
duplicity-full.20140531T230029Z.vol16.difftar.gpg
duplicity-full.20140531T230029Z.vol17.difftar.gpg
duplicity-full.20140531T230029Z.vol18.difftar.gpg
duplicity-full.20140531T230029Z.vol19.difftar.gpg
duplicity-full.20140531T230029Z.vol2.difftar.gpg
duplicity-full.20140531T230029Z.vol20.difftar.gpg
duplicity-full.20140531T230029Z.vol21.difftar.gpg
duplicity-full.20140531T230029Z.vol3.difftar.gpg
duplicity-full.20140531T230029Z.vol4.difftar.gpg
duplicity-full.20140531T230029Z.vol5.difftar.gpg
duplicity-full.20140531T230029Z.vol6.difftar.gpg
duplicity-full.20140531T230029Z.vol7.difftar.gpg
duplicity-full.20140531T230029Z.vol8.difftar.gpg
duplicity-full.20140531T230029Z.vol9.difftar.gpg

This is not good, because if the transfer is partial, they are not exploitable
(I have to sync all files 10 to 19 – and 100 to 199, 1000 to 1999 – before
transferring file 2).

Thus, I added a --numeric-sort (-N) option to rsync, to transfer the files in
the expected order.

Patch attached. Feedbacks welcome.
