Bump PKGREVISION.

* Create include/editline/history.h that is symlink to readline.h like
  NetBSD base libedit.
  This change fixes insufficient buildlinking of editline.
  So fix build of devel/elf or other editline consumer on my private
  Debian GNU/kFreeBSD pkgsrc environemnt. It should fix editline consumer
  build on other platforms.
