Agreed. Perhaps add one or two terse pointers:
1. Refer to the Library Functions Manual manpage, which gives
details exactly what things like isalpha() tests true for. This
manpage includes POSIX, _ISOC99_SOURCE etc. basis.
2. Searching for "isalpha" on Wikipedia takes me, via redirect,
to "C character classification", where each class has a brief
description. The Wiki page references:
"ISO/IEC 9899:1999 specification (PDF). p. 193, S. 7.4"
