Sets the URL hash to the address of the cursor when a user selects a diff line (either by clicking the line number or using the 'c' hotkey). If the cursor is on a line of the revision, the address is the line number. If the cursor is on a line of the base patch, the address is the letter 'b' followed by the line number. Otherwise the address is the empty string. Bug: Issue 4206 Change-Id: Ic85da197eb6264ea1111cc34e781dccbc24d4d40
