thanks for your suggestion. I applied it in attached patch. I'm 
not sure I like it though because the simplest call:

   (current-line)

is now exactly the same as (line-number-at-pos). To get a 
different behavior, non-nil must be passed as argument:

   (current-line t)

Nevertheless, I understand this implementation is probably the one 
closest to existing API and usages.

Best,
