[PATCH 0/2] submodule path handling fixes

My earlier attempt at this was misguided by my laziness, and I was willing to sacrifice correctness for the ability to move on to other problems.

So now, I taught plumbing to handle the trailing slash problem, which is not only much cleaner, but helps other users of ls-files, too.

Note that at this moment, it is beyond my reach to fix the issue that "git submodule no-such-submodule" will _only_ warn and not _fail_.

That would take a builtinification, as ls-files is used in a pipe in git-submodule.sh, and AFAIR there is no really portable way to catch errors in a pipe, short of using temporary files.

  Let ls-files strip trailing slashes in submodules' paths
