Schuyler,

Yes, that's a very good point.
I already use this feature and link my fixes on Bugzilla to
appropriate changesets on the Trac.

This way, anyone (including me) can easily check what changes exactly
have been submitted in a bug fix.
Sometimes, a bug fix introduces...new bugs :-) and next after a fix for
fix is applied, it's very helpful to see the history of bug fix changes
in readable form.


For example, I fixed a bug 1521:
http://trac.osgeo.org/gdal/changeset/10969

and in next few minutes, I found my fix was buggy, so I re-fixed it:
http://trac.osgeo.org/gdal/changeset/10975

I included both URLs in Bugzilla report for bug 1521.

In trac, when I can include r10969 in a comment and it will
automatically link.

Simply, the bug history is easily observable together with changes in
sources.

Certainly, the same can be achieved with Bugzilla and CVS diff, but Trac
makes it far easier and faster.
