The history list includes two columns of diff links next to each
revision: a 'cur' diffing against the then-latest revision, and
a 'last' link diffing against the revision immediately previous
to the one on that row.
The URLs for the 'cur' links use 'diff=0', which does the diff
against whatever the latest revision is _at the time you visit_
the URL. So if you copy and paste the URL meaning to show a
particular edit, your link will in the future show different
Now that current revisions have ID numbers in 1.5, these links
should use the actual revision number.
