comment-indent-new-line is written with a "traditional" free text style
of languages and comments, so I'm not surprised it doesn't work 100%
right under languages such as Fortran.
It's a nasty function, but I've spent a fair bit of time in it (years
ago), so I should be able to track down the problem.
