Diff by branch tag and date

[Simon Conrad-Armes]

Hi, does anyone know the current status of this feature of CVS?

Problem:
Make a checkout of a branch.
cvs co -r Feature1 module
cd module

Then you want to generate a diff, to see the changes since a specific date
on the branch.
cvs diff -d'2002/07/24' 

...however, this does not yield the expected result. Instead, cvs provides
a diff between the trunk on that date and your local copy.

Some old patches exist for cvs diff -r 'branch:date' ... style diff,
but nothing current. Is this enourmouslt useful feature still in planning?
Has it been merged into the cvs release, but under a different mechanism?
Spent hours scouring cvshome.org and google; cannot believe this is still
missing.

Thanks.
