"Set the length of fixed-form Fortran lines to NCHARS.
-This normally only affects the current buffer, which must be in
-Fortran mode. If the optional argument GLOBAL is non-nil, it
-affects all Fortran buffers, and also the default.
-If a numeric prefix argument is specified, it will be used as NCHARS,
-otherwise is a non-numeric prefix arg is specified, the length will be
-provided via the minibuffer, and otherwise the current column is used."
