As far as I can see this function iterates over all multi-line strings in a 
buffer.  That would not be safe to use for the aforementioned purpose:  There 
might be other multi-line strings in a buffer that should not be re-wrapped, 
because the line breaks therein might be significant.

I’m more looking for a solution that takes `doc-string-elt’ property of the 
current definition into account.

Thanks for your input, though
