new version of ".trunk + .origin" patch

[Stephen Cameron]

Hi,

For anybody using my ".trunk + .origin" patch,
( http://www.geocities.com/dotslashstar/branch_patch.html ):
I have a new version.  I found a tiny problem if
you specify ".origin" by itself, (which is not allowed
anyway) it would add an invalid line into the val-tags
file.

If you do, for example:

        cvs update -r .origin module

It will say you can't use ".origni" alone, but,
it will also put a bad line into the val-tags
file.

This patch to tag.c, below, (on top of the previous
complete patch) fixes that.

I also put up a new complete patch at the above
URL that includes this latest fix, and is made
relative to the current development version of 
CVS.

I noticed this problem after updating to the
recent changes to myndbm.c, which made my problem
readily apparent, (at least I think that's why it
suddenly became apparent).
