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.
Fix this by adding the --ff switch if pull.ff=true, and add a test to
catch future regressions.
Furthermore, clarify in the documentation that pull.ff overrides
merge.ff.
