I removed and did a clean checkout of the module, 
cvs checkout arrow (in directory C:\projects)
cvs server: cwd=/tmp/cvs-serv15957 ,current=/tmp/cvs-serv15957
cvs server: Updating arrow
then:
 cvs upd -jB-T-20030812 -jHEAD
On the console, I only see one file as being updated
 U images/but_continue.gif

Then I removed and did a clean checkout of the module again, 
cvs checkout arrow (in directory C:\projects)
cvs server: cwd=/tmp/cvs-serv15965 ,current=/tmp/cvs-serv15965
cvs server: Updating arrow
then reversed the branch and HEAD:
 cvs upd -jHEAD -jB-T-20030812

On the console, I see:
1. -lots of merges:
