git-mailsplit: with maildirs not only process cur/, but also new/

When saving patches to a maildir with e.g. mutt, the files are put into
the new/ subdirectory of the maildir, not cur/.  This makes git-am state
"Nothing to do.".  This patch lets git-mailsplit additional check new/
after reading cur/.
