bug#21072: Brave new mark-defun (and a testing tool)

Is a line (using C syntax) like:

    /* blablabla

considered as a "comment line"?
What about the likely next line:

    blablabla */

?
How about

    blablabla

on a line between the previous two (i.e. within a comment)?

Regardless of the answer you give above, I'm wondering in which kind of
circumstance we'd want to test if we're on "a line containing only
a comment".
