Use format-as-you-type for Paredit

[PEZ]

When formatting, Calva has two basic ”modes”:

1. On demand: Strictly follow the users settings
2. On type: The users settings, but relax trimming surrounding and trailing whitespace, and, consecutive blank lines.

The formatting that happens with Paredit is, as I see it, format-as-you-type. But Calva doesn't treat it that way, and instead uses on-demand formatting. Why? I don't remember why. Could be an honest mistake. Could be some good reason. Although, I really can't think of the reason.

As things are, we get issues like this one:

• Calva Paredit: Kill/Delete Right deletes also the space before the form #1922

I think we should try format-as-you-type for Paredit, even for a release, and see what the feedback is. We might find some cases where we miss some whitespace trimming, but I am guessing that we will be able to fix those, case by case, rather than going back to on-demand format.
