get_maintainer: very noisy since '-f' is optional

Hi Joe,

commit 4cad35a7ca690eabf0d241062ce9e59693ec03e7 ("get_maintainer.pl:
reduce need for command-line option -f") makes my scripts very noisy.

I regularly use get_maintainer to create CC lists for patch series generated with coccinelle. These patch series are stored outside my Linux git repo. Now I get for every vcs_file_exists() a warning from git-ls-files:

fatal: /home/wsa/Kernel/string-refactor/usb_alloc_urb/patches/sound/usb/0001-ALSA-usb-caiaq-audio-don-t-print-error-when-allocati.patch: '/home/wsa/Kernel/string-refactor/usb_alloc_urb/patches/sound/usb/0001-ALSA-usb-caiaq-audio-don-t-print-error-when-allocati.patch' is outside repository

Git version 2.8.1 here.

Can you take care of that?

Thanks,

Wolfram

Hi Wolfram.

One of my favorite xkcd comics: https://xkcd.com/1172/

Maybe this?

index 49a00d5..aed4511 100755

Yes, a good one. I hope my usecase of checking patches outside the repo is not as esoteric, though ;)

Seems to work. Thanks!
