Nik Clayton 26dabb6003 From the PR:
1. ctype.h defines digittoint(), isnumber() and ishexnmber(), yet
        they are not documented in any of the manpages.

        2. The ctype manpage references a non-existent manpage for
        digittoint().

        3. The isascii() manpage claims it is standards compliant, when
        it isn't.

        4. isblank() claims it is _not_ standards compliant, when it
        is.

Fix by including the appropriate .Nm entries, and with a new digittoint.3
page.
