$NetBSD: patch-au,v 1.1.1.1 2010/09/12 03:50:06 taca Exp $
Defer loading readline, when it is really needed.
Some unknown reason:
1. build devel/ruby-readline with editline(3).
2. Execute a ruby script loading readline in background from shell.
3. When the script output something to stdout, it got SIGTSTP and suspends.
There is no such problem when build devel/ruby-readline with GNU's readline.
