For short single commands, prefer a one-liner `for` with the zsh syntax:
```
for x (foo bar) print ${x}
```
Otherwise just place `; do` on the same line as the POSIX `for ... in`:
```
for x in foo bar; do
print ${x}
done
```

and use `-F` to check if the feature was not already loaded before.
Use terminfo elements for Backspace and Delete. Sort by terminfo element
keys.
Also simplify code, removing unnecessary double quotes, and replacing
if-then-fi with one command by one-liners.
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
