--- Comment #1 from Mikael Morin <mikael at gcc dot gnu.org> ---
gcc's invoke.texi looks like:
@opindex fpic
@cindex global offset table
@cindex PIC
@item -fpic
whereas gfortran's invoke.texi has:
@opindex @code{ffree-form}
@opindex @code{ffixed-form}
@cindex options, Fortran dialect
@cindex file format, free
@cindex file format, fixed
@item -ffree-form
@itemx -ffixed-form
I haven't found this @opindex in the texinfo manual, but it seems plausible
that fixing the nested <code> in the generated html would be as simple as
removing the @code as argument of @opindex.
