Guy, you are perfectly right,
however I think it should be possible to replace the call

 ary = rb_funcall(proc, rb_intern("call"), 1, rb_tainted_str_new2(text));
in
 static char **
 readline_attempted_completion_function(text, start, end)
in
 ext/readline/readline.c

with a call that also provides rl_line_buffer to the Proc.

OR 

maybe extending the Readline module to provide read access to
rl_line_buffer at any time during the use of Readline.

It don't which one is easier to implement.

But as a matter of fact, C coders have access to this rl_line_buffer
variable even when they are in the completion callback, haven't they ?
