checking for a working System.Console.Readline

>| readline

Since you mention readline - I have a rather tiny nit to pick: ghci
happily completes filenames starting with ~ (indicating home
directory), but file operations typically don't grok it.

As I said, hardly an earth shattering show stopper, but a small wart
that might be easy to remove?
