This way you would match on _any_ pattern looking like a RCS tag.
But I'd rather enumerate the ones explicitely (we noticed "Id"
and "FreeBSD"). I don't actually know that there are some tags
of special interest or even dangerous to ignore, but I would play
it safe.
If you want to cut corners and match with a "bigger" or more
general pattern, you could as well 'ident $FILE > $PATTERNS' and
have them collapse like this (it's a sketch, not real code)
cp $FILE $TEMP
while read P; do
P=`echo "$P" | sed 's/^ *//; s/ *$//'` # needed?
cat $FILE | sed 's/\('"$P"'\)/$TAG$/' > $TEMP.1
mv $TEMP.1 $TEMP
done < $PATTERNS
Plus for the other file and the comparison of the two temporary
results.

Look at "man 7 re_format" :) There's some [0-9]{4} notion. The
thing is referred to as a "bound".
