Of what use is this feature? Where is the URL created? In the changelog?
The changelogs don't really need the URL, and IMHO would just be clutter.

We _should_ be able to create a changelog entry from either source
field, e.g., 'Bug:' or 'BugLink:'. Its probably also worthwhile to make
the field detection case independent. Furthermore, if both fields exist,
they had better reference the same bug.

Sounds right.
