     Revert r42636. That hack is no longer needed now that we removed the compact
     location bar view.

     git-svn-id: svn://svn.chromium.org/chrome/trunk/src@52935 0039d316-1c4b-4281-b951-d872f2087c98

 Will be parsed to map svn revision r52935 (on Google Code) to commit
 016d28b8c4959a3d28d2fbfb4b86c0361aad74ef. The parsing will generate a lot of
 lines that look like `rXXXX = 01234ABCD`. It should generally take a minute or
 so when doing an incremental update.
 
 For this to work, two things must be true:
 
 *   The svn url in the `svn-remote` clause must exactly match the url in the
     git-svn-id pulled form the server.
 *   The fetch from origin must write into the exact same branch that specified
     in the fetch line of `svn-remote`.
 
 If either of these are not true, then `git svn fetch` and friends will talk to
 svn directly, and be very slow.
 
 ## Reusing a Git mirror
 
 If you have a nearby copy of a Git repo, you can quickly bootstrap your copy
 from that one then adjust it to point it at the real upstream one.
 
 1.  Clone a nearby copy of the code you want: `git clone coworker-machine:/path/to/repo`
 1.  Change the URL your copy fetches from to point at the real git repo:
-    `git set-url origin http://src.chromium.org/git/chromium.git`
+    `git set-url origin https://src.chromium.org/git/chromium.git`
 1.  Update your copy: `git fetch`
 1.  Delete any extra branches that you picked up in the initial clone:
     `git prune origin`
