Assuming a complete checkout, with -rBASE specified, the same set of 
files would be tagged, with the possible irrelevant exception of any 
files where a dead revision got tagged, but I'm not sure a dead revision 
would be tagged anyhow.

The case I am worried about is 'cvs tag -r release_1-0 -b maint_branch'. 
Why should that command behave differently in a sandbox checked out 
from project than 'cvs rtag -r release_1-0 -b maint_branch project', 
when a 'cvs up -r release_1-0' would generate the initial set of files 
rtag tagged as the base of the branch and the set of files tagged by the 
first (tag) command could be missing some files:

   cvs co -l .
   mkdir project
   cvs add project
   cd project
   touch file1 file2
   cvs add file1 file2
   cvs ci -maddem
   cvs tag release_1-0
   cvs rm -f file2
   cvs ci -mbyebye
   cvs tag -rrelease_1-0 -b release_1-0_maint


will only tag file1.  Please name even a single case where that is 
useful.  Note that replacing the last tag command above with 'cvs up 
-rrelease_1-0' would pull down file1 and file2.
