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. PR: docs/26451 Submitted by: Adrian Filipi-Martin <adrian@ubergeeks.com>
