- `mode_sequence` (`ms`) -> `align` (`a`)
- `stick_to_left` (`<` / `s01`)
This commit does not break backward compatibility.
`mode_sequence` is still allowed.
This commit adds LiveEasyAlign command. (The name was chosen not to introduce
ambiguity when typing in only the prefix of the command: e.g. `:EasyA*|`)
In live interactive mode, the selected text is aligned on-the-fly as the user
type in. In order to finalize the alignment, the user has to type in the
same delimiter key again. (Or CTRL-X on regular expressions)
