Thanks, but could you perhaps post a recipe for reproducing the
warning?  Based on your description, I couldn't understand how to
reproduce it: which variables to change (with the single exception of
bug-reference-url-format), and what should be the buffer text to
trigger the warning.  Could you help me reproducing the problem, so I
could investigate it and see how to fix it?
