git mv: do not keep slash in `git mv dir non-existing-dir/`js/mv-dir-to-new-directory
When calling `rename("dir", "non-existing-dir/")` on Linux, it silently
succeeds, stripping the trailing slash of the second argument.
This is all good and dandy but this behavior disagrees with the specs at
http://pubs.opengroup.org/onlinepubs/9699919799/functions/rename.html
that state clearly regarding the 2nd parameter (called `new`):
If the `new` argument does not resolve to an existing directory
entry for a file of type directory and the `new` argument
contains at least one non- <slash> character and ends with one
or more trailing <slash> characters after all symbolic links
have been processed, `rename()` shall fail.
Of course, we would like `git mv dir non-existing-dir/` to succeed (and
rename the directory "dir" to "non-existing-dir"). Let's be extra
careful to remove the trailing slash in that case.
This lets t7001-mv.sh pass in Bash on Windows.
