warning: NULL value for key

[Cameron, Steve]

Hi,

Just wondering if this is normal:

I have two non-branch tags, "superset" and "subset" 
and an alias module.

The "superset" tag points to the same revisions
of the same files as "subset", but also points
to revisions of some extra files not in subset.

The alias module contains the exact set of files
which "subset" points to.

The files in superset which are extra, (not
in subset) give a warning message:

cvs rdiff -s -r superset -r subset alias_module 
cvs server: warning: NULL value for key `dir1/file1`
cvs server: warning: NULL value for key `dir1/file2'
cvs server: warning: NULL value for key `dir2/fileA'
cvs server: warning: NULL value for key `dir2/fileB'

Maybe the answer is I should just ignore the warnings...

I expected no differences, as the alias_module
should have excluded the files in superset which
are not in subset from being considered since
subset == alias_module, (or so one might expect.)

This is cvs 1.10.8 on redhat linux (7.0, I think)
(fresh checkout of development version today, 7/26/2001, 
behaves the same way.)
