[cvsnt] RFE:Parameter similar to "-f" on update command

[Henrik Wahlberg]

I was looking for a parameter to the update command, (when updating to a 
  sticky revision) to leave files not carrying the tag as they are.

It should be somewhat similar to the -f option, but instead of taking 
the latest from head when the file isn't carrying the tag in question, 
it should leave the files as they are (possibly sticky tagged to some 
other revision).

Oliver Giesen suggested me to post a rfe. Hope it's the correct place 
and my explanation is adequate.

-----------------Example----------------
Aim. Build a release for Costumer_A based on the general release tagged 
IFS_711

The file CosIniFile.java is in rev 1.66 on head, and carries the tag 
IFS_711 on rev 1.60.

On the root of my sandbox I'd update to IFS_711:

cvs -q update -P -r IFS_711

which would bring the source tree to this release. (and in particular
CosIniFile to rev 1.60)
then I was hoping to be able to do something similar to:

cvs -q update -P -f -r Costumer_A

to have those file carrying the "Costumer_A" tag updated, leaving other
files at the IFS_711 revision.
Unfortunately (in my situation) the other files are replaced with
head.

P.S.
A bit to my surprise, after doing these two steps, WinCVS is indicating 
  files not carrying the Costumer_A tag, as stickyTagged to Costumer_A, 
a tag not existing on any of them, whereby the next normal update would 
remove most of the files.

TIA.
