Subject: git-clean: Fix error message if clean.requireForce is not set.
X-Git-Tag: v1.5.4-rc0~153^2~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=625db1b7530b621f32b0ef1ef502a09a05872f5d;p=git.git

git-clean: Fix error message if clean.requireForce is not set.

It was distracting to see this error message:

     clean.requireForce set and -n or -f not given; refusing to clean

even though clean.requireForce was not set at all. This patch distinguishes
the cases and gives a different message depending on whether the
configuration variable is not set or set to true.
