Git used to trim the trailing slash, and make the command equivalent to
'git mv file no-such-dir', which created the file no-such-dir (while the
trailing slash explicitly stated that it could only be a directory).
This patch skips the trailing slash removal for the destination path. The
path with its trailing slash is passed to rename(2), which errors out
with the appropriate message:
$ git mv file no-such-dir/
fatal: renaming 'file' failed: Not a directory

So, this patch adds more tests, as suggested by Duy. They all pass
without modifying the code.
