Bug description:
readline_set_completion_display_matches_hook_impl will use either VFunction (if _RL_FUNCTION_TYPEDEF is defined) or rl_compdisp_func_t. The former is deprecated but available in current readline, while the latter has historically not been available in libedit. However, libedit recently added rl_compdisp_func_t and removed VFunction entirely: http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libedit/readline/readline.h.diff?r1=1.53&r2=1.54&sortby=date
We ship a recent libedit in MacPorts, so we see a compilation failure like this:
./Modules/readline.c:448:10: error: use of undeclared identifier 'VFunction'; did you mean 'function'?
(VFunction *)on_completion_display_matches_hook : 0;
^~~~~~~~~
It's easy enough for us to patch around this, but I guess if compatibility with both current libedit and the older version shipped by Apple is desired, there needs to be another check for the availability of this type.
