>Description:
        
I am trying to use cvs log to list all of the revision logs made
between two versions of an application, as a basis for writing release
notes.

Since each application version has a tag, I should be able to do:

cvs log -rv1_tag::v2_tag

Unfortunately this doesn't work when the first tag is at the base of a
branch (e.g. v1.0 of the app) and the second tag is on that branch
(e.g. v1.1 of the app).

I get the following error:

% cvs log -N -rv1_0::v1_1 foo
cvs server: invalid branch or revision pair v1_0:v1_1 in `/pgrd/ljdev/cvsroot/TE
STME/foo,v'


>How-To-Repeat:

% echo "line 1" > foo
% cvs add foo
cvs server: scheduling file `foo' for addition
cvs server: use 'cvs commit' to add this file permanently
% cvs ci -m 'line 1' foo

done
Checking in foo;
/pgrd/ljdev/cvsroot/TESTME/foo,v  <--  foo

done
% cvs tag v1_0 foo
T foo
% cvs tag -b v1_branch foo
T foo
% cvs update -r v1_branch foo
