cvs annotate and branches

[Andrew Johnson]

Can anyone explain why  cvs annotate  makes use of some information from a
sandbox (repository location etc.), but doesn't look at its sticky tags? 
While the actual behaviour (CVS 1.11) does match the documentation, it
seems strange that I have to explicitly add  -r BRANCH_xx  to get it to
DWIM when working on a branch.

Could/should this be changed?  Easily?
