Questions about r and (r ...)

[FrauH0lle]

When I started using regions in my templates, I came up with some questions.

Tempo's documentation in tempo-define-template says about r:
The symbol r: If tempo-insert is called with ON-REGION non-nil the current region is placed here. Otherwise it works like p.

Whereas Tempel's r states
If no region is active, quits the containing template when jumped to.

I guess the different behavior is intentional thus, what would be the correct way to have a field in the template which is optionally a region and otherwise a normal placeholder?

(section-box
 >
 (p (if (string-suffix-p " " comment-start)
                          comment-start
                        (concat comment-start " ")) cs t)
 cs (make-string (- fill-column (current-indentation) (length cs)) ?-) n>
 cs (r "default title") n>
 cs (make-string (- fill-column (current-indentation) (length cs)) ?-) n>
 p n>
 q)

When I use the template above, I get the default value when no region is active:

However, in case there is a region

I expected that the region replaces the default value. Is this intentional?

Most likely this feature doesn't exist.

Are you sure? I don't see this issue.
