Yes, it will, I neglected to mention that.

Yes, that will work the way you expect. The only thing I can think of that
might mess that up would be a file that happens to have a filename that
contains the same text as the tag. Anchoring the tag with the
beginning-of-line followed by a tab should handle that - I'm not conversant
enough with grep to figure out how to tell grep to match a tab character
though :-)

In any case, that's nicer than my version.

I left that as "an exercise for the reader" >:->

Yes, we (at my work) have always considered that a fairly significant
weakness in CVS - there is no logging of changes to tags (at least, not out
of the box - you could use CVSROOT/taginfo to create and maintain a log file
of changes to tags). It's a little too easy to move or delete tags.
