Commit auto-links in bugzilla comments

[Milan Crha <mcrha redhat com>]

        Hello,
I'd like to ask: how does the auto-links for commits in the new 
bugzilla work? I mean, if I write something like:
   commit abcde12345
then the "abcde12345" will become a link to the sources in the product 
the current bug is filled for. It works similarly to bug auto-link 
references, which is nice.

My problem is when one change for a product A requires also a change 
in product B and I reference commits for both products within one bug 
report. That may cause one of the commit links invalid.

Is there a way to tell the comment parser that the commit itself 
belongs to another product than the one the bug is filled for?

        Bye,
        Milan
