Support explicit register for :, |, ! and $ commands

Giving an explicit register uses its content for the default value
to use if the user does not enter anything. This enables:

`set-register a %{commands}; execute-keys '"a:<ret>'`
`set-register a %{shell script}; execute-keys '"a|<ret>'`
...

This provides a nice way to avoid the need to escape keys to use
those normal mode commands.

Fixes #3825
