description:
On the sed expression used to extract $NetBSD$ and $Id$ tags, add
a "^" to the beginning to anchor the expression.  No change in the ouput
but on SunOS-5.9 it runs up to 90,000 times faster on some files (probably
much less of an improvement on some, maybe more improvement on others).
Committed during the freeze as bulk builds that call 'make debug' were
unusable.
