Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

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.
