From d2fd119c4fcaea266a894354b506959376140c37 Mon Sep 17 00:00:00 2001 From: "Michael G. Schwern" Date: Sat, 28 Jul 2012 02:47:50 -0700 Subject: [PATCH] git-svn: introduce add_path_to_url function Remove the ad-hoc versions. This is mostly to normalize the process and ensure the URLs produced don't have double slashes or anything. Also provides a place to fix the corner case where a file path contains a percent sign.
