Fix bug linkification.
Review Request #6276 — Created Aug. 26, 2014 and submitted
The change to the bug tracker URL format strings (using "--bug_id--" instead of
"%s") was made in most places, butRB.LinkifyUtils.linkifyBugs
was missed. This
change fixes that.
Put some bug links in text fields (description, comments, review header/footer)
and saw that the links were correct both when initially loading the page and
when making changes.
