[PATCH 1/4] t7601: test for pull.ff=true overrides merge.ff=false

[Paul Tan <pyokagan@gmail.com>]

Since b814da8 (pull: add pull.ff configuration, 2014-01-15), running
git-pull with the configuration pull.ff=false or pull.ff=only is
equivalent to passing --no-ff and --ff-only to git-merge. However, if
pull.ff=true, no switch is passed to git-merge. This leads to the
confusing behavior where pull.ff=false or pull.ff=only is able to
override merge.ff, while pull.ff=true is unable to.

Add a failing test that demonstrates this case.
