The file is renamed to no-such-dir without the slash at the end. The
updated commit message would be:
mv: let 'git mv file no-such-dir/' error out on Windows, too
The previous commit c57f628 (mv: let 'git mv file no-such-dir/' error out)
relies on that rename("src", "dst/") fails if directory dst does not
exist (note the trailing slash). This does not work as expected on Windows:
The rename() call does not fail, but renames src to dst (without the
trailing slash). Insert an explicit check for this case to force an error.
This changes the error message from
$ git mv file no-such-dir/
fatal: renaming 'file' failed: Not a directory
to
$ git mv file no-such-dir/
fatal: destination directory does not exist, source=file, destination=no-such-dir/
