This function is always called with a relative_path that ends in a slash, so there's no need to insert a second one. So, don't. Instead, add an assertion to verify that nothing gets broken in the future, and adjust the comments. While this is not a critical bug, the duplicate slash is visible in error messages, which could create confusion, so back-patch to v17. This is also better in that it keeps the code consistent across branches. Patch by me, reviewed by Bertrand Drouvot and Amul Sul.
