I was almost certain that git won't let me send the same patch twice, but today I've managed to double-send a directory by a mistake: git send-email --to linux-kernel@vger.kernel.org /tmp/timens/ --cc 'Dmitry Safonov <0x7f454c46@gmail.com>' /tmp/timens/`
[I haven't noticed that I put the directory twice ^^]
Prevent this shipwreck from happening again by asking if a patch is sent multiple times on purpose.
