Fortran Indentation and Filling Commands
........................................

`C-M-j'
     Break the current line and set up a continuation line
     (`fortran-split-line').

`M-^'
     Join this line to the previous line (`fortran-join-line').

`C-M-q'
     Indent all the lines of the subprogram point is in
     (`fortran-indent-subprogram').

`M-q'
     Fill a comment block or statement.

   The key `C-M-q' runs `fortran-indent-subprogram', a command to
reindent all the lines of the Fortran subprogram (function or
subroutine) containing point.

   The key `C-M-j' runs `fortran-split-line', which splits a line in
the appropriate fashion for Fortran.  In a non-comment line, the second
half becomes a continuation line and is indented accordingly.  In a
comment line, both halves become separate comment lines.

   `M-^' or `C-c C-d' runs the command `fortran-join-line', which joins
a continuation line back to the previous line, roughly as the inverse
of `fortran-split-line'.  The point must be on a continuation line when
this command is invoked.

   `M-q' in Fortran mode fills the comment block or statement that
point is in.  This removes any excess statement continuations.
