Subject: add-patch: quit on EOF
X-Git-Tag: v2.52.0-rc0~6^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e56f6dcd7b4c90192018e848d0810f091d092913;p=thirdparty%2Fgit.git

add-patch: quit on EOF

If we reach the end of the input, e.g. because the user pressed ctrl-D
on Linux, there is no point in showing any more prompts, as we won't get
any reply.  Do the same as option 'q' would: Quit.
