[texhax] Custom justification (for captions)

I’m trying to emulate a particular justification style.  (This is for
figure captions with the caption package.)

Specifics are:
Large left margin, flush to right margin, fully justified, EXCEPT---
if there’s only one line, it is to be right-justified.


        Figure 2  ’Twas brillig & the slithy toves
        did gyre and gimble in the wabe; all mimsy
        were the borogoves.

                           Figure 3 Short caption.

I have most of what I need with


except for the odd one-line justification rule.

I’m not sure how best to implement this.  Having read the caption
package docs, I think I’ll either need to write something like


--- but what goes in the {...}? --- or else a custom caption format like


where the "..." is some sort of very stretchable glue.

What would be the best way to accomplish this?
