Fix default Alt+W keybinding (#6110)

Browse Source 
* Fix default Alt+W keybinding

The old keybinding would chop off the last line of the `whatis` output
when using a multi-line prompt. This fix corrects that.

* Make variable local and remove unneeded if statement

* Test that token is non-empty
