[cvsnt] Checkout single file with tag does not always work

[John Rushworth]

Hi,

As part of a simple clean build system we are using we sometimes want to
check out tagged versions of single files to a specified directory:

	i.e. cvs co -d tmp_dir -r tag_name filename

Frustratingly, for some files it works, and for others it doesn't!!!

For files where it doesn't work we get:

	cvs server: in directory .:
	cvs [server aborted]: there is no version here; do 'cvs checkout' first

This is bad enough, but it also removes tmp_dir from the client machine...
D'oh!

Both of the listed command line clients give the same results

	Client: Concurrent Versions System (CVS) 1.11.2 (client)
	Client: Concurrent Versions System (CVSNT) 1.11.1.3 (Build 72)
(client/server)
	Server: Concurrent Versions System (CVSNT) 1.11.1.3  (Build 57h)
(client/server)

I had a search back through the archives and found references to similar
problems:
	http://www.cvsnt.org/pipermail/cvsnt/2002-June/002339.html
	http://www.cvsnt.org/pipermail/cvsnt/2002-August/003195.html
	http://www.cvsnt.org/pipermail/cvsnt/2002-November/003936.html

but no answers....

This seems like a reasonably basic sort of request to make and, whilst I am
new to CVS, I would have expected it to just work.

Is this a bug, or am I doing something wrong?

I have included some traces....
