+Issues in need of work. Mostly compatibility with GNU readline, BSD libedit,
+http://www.thrysoee.dk/editline/, and usability improvements.
+
+Remember, the general idea is to keep Minix editline small.
+
+* Verify for 1.14.0 that custom completion handlers still work
+After reverting "fix" in 0.2.2 that made rl_complete() a function pointer we need to
+make sure the same functionality is still available with the new infrastructure.
+(Which is more inspired by BSD libedit and GNU readline.
+
+* Investigate GNU readline dependencies needed for "fileman" example
+The BSD libedit library has imported the GNU readline "fileman" example into its
+tree to demonstrate the abilities of that library.  This would also be quite useful
+for Minix editline.
+
+The first task is to investigate the depependencies and form TODO list items
+detailing what is missing and, if possible, proposals how to implement including any
+optional configure flags.
 
-* Verify for 1.14.0 that custom completion handlers still work, after reverting fix in 0.2.2.
-* Port "fileman" example from BSD libedit, http://www.thrysoee.dk/editline/
 * Instead of supporting multiline input, try the Emacs approach, line scrolling.
+
 * Add support for rl_bind_key(), currently only en editline specific el_bind_key() exists.
+
 * Add support for inhibiting completion: rl_inhibit_completion
+
 * Make "char *rl_prompt" globally visible.
+
 * Add support for rl_set_prompt().
+
 * Add support for --enable-utf8 to configure
+
 * Use strcmp(nl_langinfo(CODESET), "UTF-8") to look for utf8 capable terminal.
+
 * Implement simple UTF-8 parser according to http://www.cl.cam.ac.uk/~mgk25/unicode.html#utf-8
