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.

.Sh SYNOPSIS
.Fd #include <ctype.h>
.Ft int
.Fn digittoint "int c"
.Sh DESCRIPTION
The
.Fn digittoint
function converts a numeric character to its corresponding integer value. The
character can be any decimal digit or hexadecimal digit. With hexadecimal
characters, the case of the values does not matter.
.Sh RETURN VALUES
The
.Fn digittoint
function always returns an integer from the range of 0 to 15. If the
given character was not a digit as defined by
.Xr isxdigit 3 , the function will return 0.
