Yes, some kind of flag
-r re-add/cancel the removal?
or e.g.
-f force addtion after removal
would at least partially solve the problem, but only for an attentive user.
And actually as info cvs says:
"   If you execute `remove' for a file, and then change your mind before
you commit, you can undo the `remove' with an `add' command.

     $ ls
     CVS   ja.h  oj.c
     $ rm oj.c
     $ cvs remove oj.c
     cvs remove: scheduling oj.c for removal
     cvs remove: use 'cvs commit' to remove this file permanently
     $ cvs add oj.c
     U oj.c
     cvs add: oj.c, version, resurrected"
it should work without any options anyway. Perhaps we have an outdated version 
(Concurrent Versions System (CVS) 1.11.1p1 (client/server)) at our university 

We still have the problem that if some file is 'cvs remove'd locally it will 
be removed regardless of the fact that it might have been changed.
There are actually 2 possibilities for the file to be changed:
1. before cvs remove
Since the 'cvs remove file.txt' doesn't work as long as the file is there,
user tend to use 'cvs remove -f'. Problem: user has to check manually if the 
file.txt has been changed. Wouldn't it be nicer if 'cvs remove' would work 
(and delete local copy, too, if it is invoked with a filename) as long as 
file.txt is unchanged (local test on timestamps)? If file.txt has not been 
changed and then deleted by accident, it could be easily regenerated by 'cvs 
'cvs remove -f' would then be used to force deletion, i.e. I know I have 
changed the file and do not want to keep neither the changes nor the file 
(and I do not want to hear any complaints, since I use a force flag).

2. after cvs remove
We have a remove timestamp in CVS/Entries. If file.txt is recreated after that 
timepoint we should regard it in special way when 'cvs commit'ting 
(regardless of the option that was used in 1).
Either 'cvs commit' should stop and say the same thing that 'cvs remove' 
currently says:
  file.txt still in working directory
  1 file exists; remove it first
  it should at least backup those files with .# prefix as this is done during 

Offtopic: wouldn't it be nice if the mail archive 
http://mail.gnu.org/archive/html/bug-cvs/ would have some button/link to 
reply to the mailing list? One then wouldn't need to subsribe to it to allow 
proper indentation of the own messages.
