[PATCH 1/5] merge-recursive: find-renames resets threshold

["Felipe Gonçalves Assis" <felipeg.assis@gmail.com>]

Make the find-renames option follow the behaviour in git-diff, where it
resets the threshold when none is given. So, for instance,
"--find-renames=25 --find-renames" should result in the default
threshold (50%) instead of 25%.
