bug#22262: 24.5; case-fold-search breaks fortran comment regexp

[Tadeusz J Liszka <tad@altair.com>]

use of (setq default-case-fold-search nil) breaks fortran comment
recognition mechanism.

Fortran Comment Line Start Skip is set to default regexp containing both
cases of c and d: ^[CcDd*!].... however when the above setq is in
.emacs, then comments starting with caps C or D are not recognized
