isascii: stop using it * doc/pastposix-functions/isascii.texi: There is no isascii module. * m4/mbswidth.m4 (gl_MBSWIDTH): Do not check for isascii, as it no longer seems to be used here. * tests/test-c-ctype.c (test_agree_with_C_locale): Do not assume isascii exists, as POSIX no longer requires it.
