Linus Torvalds 0940e5f211 diffcore-rename: properly honor the difference between -M and -C
We would allow rename detection to do copy detection even when asked
purely for renames.  That confuses users, but more importantly it can
terminally confuse the recursive merge rename logic.

test_description='More rename detection tests.
The rename detection logic should be able to detect pure rename or
copy of symbolic links, but should not produce rename/copy followed
by an edit for them.
