as `expand-or-complete-with-redisplay` was added to fix an issue
reported with zsh 5.2 when completing with <Tab><Tab><Ctrl-C>. See #85.
Fixes#134. Closes#256
The issue is fixed by adding `zle redisplay` after `zle
expand-and-complete` for the expand-and-complete key binding. An
additional `print -n '...'` is also included to show an indicator while
the menu is loading, and that is purely cosmetic.
There's still one glitch: the prompt jumps one line up after
<Tab><Tab><Ctrl-C>. This was observed in Prezto too.
Fixes#85, closes#89
Only bind keys if length of var > 0
Hopefully these are the only keys that will require this testing. If
anyone encounters issues like issue #17 with additional keys, please
create an issue.
Closes#17
