* 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.
Based on wip/editline by reed@.
This is an autotool- and libtoolized port of the NetBSD Editline library
(libedit). This Berkeley-style licensed command line editor library
provides generic line editing, history, and tokenization functions,
similar to those found in GNU Readline.
