There's a step you left out - before the remove, 'cvs update -r
my-release-1-0'. This gives much more, er, interesting results:

Adding file


Note that the log shows the state of 1.1 as Exp, and the tag has
disappeared. Basically, it looks like a "cvs remove" when there's a sticky
tag in effect acts the same as a "cvs tag -d [tag]". You get the same
results even if there's a revision 1.2, i.e.:

cvs add file
cvs tag atag file
[modify file]
cvs ci file
cvs up -r atag
cvs remove -f file
cvs ci file
cvs log file (will show 1.1 and 1.2 as state: Exp, no symbolic names).

This is using CVS 1.11.9 (I know, I know, it's old). I didn't see anything
in the NEWS file to indicate this problem has been fixed.
