For fun, I scrolled back through WebCore/ChangeLog looking for a
non-build fix that was missing a bug link.  The first one I found was
160 revs ago.  I suspect the vast majority of patches already have bug
reports.

We require a ChangeLog for every patch.  Isn't that a TPS report?

Another perspective is that we have lots of tools to help you not
break the build.  If you bypass those tools and break the build,
you're going to piss people off.

Please be kind, rewind.  (Well, or switch to watching movies on DVD.)
