#17 check for readline version

[Anonymous]

There's obviously a dependency to a recent version of
readline, you may want to add a corresponding check to
configure.in, so as to avoid problems such as these:

There's a problem in the readline check specified in acinclude.m4.
The check fails because the function rl_function_of_keyseq isn't in Readline 5.2 (current as of Oct,2006).
Modifying acinclude.m4 to check for rl_completion_append_character instead fixes this problem (this is a check for readline > 2.1).
