   So a key is pressed when there is no visible input on the current
display line (which isn't the same as position 0 in the current input line),
now say that key is the complete key.  Say I want to either insert the
the complete key OR call the complete function based on where the
input position is on the physical (screen) line and what came before
it.  (shell-state, current input, and current input column among other
things).

   bash used to not do complete on an empty physical line, but
it was pointed out that one could be on an empty physical line, and
still want complete, so one no longer has the ability to paste into
bash, cleanly.  It eats input chars.

   I prefer to be able to paste than to be able to press complete when
the physical line is in col 0 or only whitespace preceeds the complete
key.

Seemed like it might be a way to get this done if there was sufficient
flexibility between the rl & bash layers.
