It is only hack for application which wants to have readline and they
don't detects libedit. Finally it is like:
#include <editline/readline.h>
#include <editline/readline.h>
I little bit searching on Internet and it seems that when edit/history.h
exists it is link to editline/readline.h. (See e.g.
http://sysinf0.klabs.be/usr/include/editline/history.h?dist=;arch= )
This link is created by packager, because when you compiling libedit,
make install does not create it.
By my opinion HAVE_EDITLINE_HISTORY_H is overhead, but we can keep it.
