Ok, done, see attached patch.

Also done.

Ok, so now the N is considered for delete-space-after/before with the
meaning to keep N whitespace characters after/before point and only
delete surplus ones. However, that has one major drawback: now you
cannot delete all whitespace including newlines before/after point
because that would require you to provide (zerop N) and (< N 0) at the
same time.
What do you think? I mean, one solution would be to add just more
actions, e.g., rename the ones considering the actual numeric value of N
to delete-all-but-n-space-after/before (plus variants considering
newlines, too) and have delete-space-after/before as previously where
only N positive/negative is checked to control if newlines are
considered or not.
