Oups.  Fixed on master.

But anyhow, I don't see how bug-reference-fontify could be so costly
GC-wise...

FWIW, I think goto-address-mode (buttonizing URLs and email addresses)
will probably have the same effect, at least the code looks pretty
similar.  Can you confirm?

I'll have a look at you sample file tomorrow.  How do you make GCs
"visible" so that I can see when excessive GCing starts/stops?
