Tweak regex to avoid a bug in Perl 5.16.3.

For some reason, 5.16.3 (and perhaps slightly earlier/later versions)
go into an infinite loop with the version-replacement regex installed
by commit fc0d0ce97.  We can work around that by using an explicit
"\n" instead of the line-start metacharacter "^".
