Arguments, if any, are ignored.
This function returns the “index” of the cursor's position in the “current” input line ($L).
As with all “index” values, counting starts from zero.
Counting begins after the input prompt, if any.
The “current” input line is the last screen to receive a key-press. If you use this function outside of a key binding, this may be an important consideration. Use within a key-binding should be safe.
This function is used, in conjunction with $indextoword() to retrieve the
word “under” the cursor. This is most useful with tab completion.
This function first appeared in ircII-2.2.2.
