Patch 659834 by Magnus Lie Hetland:
Check for readline 2.2 features. This should make it possible to compile readline.c again with GNU readline versions 2.0 or 2.1; this ability was removed in readline.c rev. 2.49. Apparently the older versions are still in widespread deployment on older Solaris installations. With an older readline, completion behavior is subtly different (a space is always added).
