removing a revision

[Igor Schein]

Hi,

let's say I have 4 revisions of a file, 1.1, 1.2, 1.3 and 1.4, and I
want to wipe out rev 1.2 completely, shiting the later 2 revisions:

1.1->1.1
1.2->gone
1.3->1.2
1.4->1.3

I can do cvs admin -o 1.2 filename, but I can't figure out an easy way
to shift the other 2 revisions.  The only way I came up with is:

cvs co -r1.3 dir/filename
cp dir/filename filename-1.3
cvs co -r1.4 dir/filename
cp dir/filename filename-1.4
cvs admin -o 1.3 dir/filename
cvs admin -o 1.4 dir/filename
rm -r dir
cvs update -A -d dir
cp filename-1.3 dir/filename
cvs ci -m "" -r 1.2 dir/filename
cp filename-1.4 dir/filename
cvs ci -m "" -r 1.3 dir/filename

but it feels very unnecessary.  There're should be an easier way. To
preclude possible question, I do have a need to remove a middle
revision completely, even if such action is not in sync with CVS's
spirit.

Thanks in advance.

Igor
