Subject: [PATCH] Strip trailing slashes from URLs

Previously if you had a remote in the format:

https://github.com/owner/repo/

When using Gbrowse from fugitive, there would be double slashes in the
opened URL:

https://github.com/owner/repo//blob/master/README.md

This caused GitHub not to show a preview of the lines inline if you
posted it in a comment. This change strips the trailing slash if it
exists.
