I'd much much prefer having a description of the problem in the actual
comment then a hyperlink.  There's just too much chance of the latter
breaking over time, and it's impossible to update it when things change
that should be reflected in the comment.

The actual commit text is very good though, but I agree - I don't think
the url comment is worth anything. I did consider just killing it.
However, the comment does describe the problem, so I think it's still
ok.

I thought the whole story was too long for the comment.  Feel free to
kill or edit it.
