Author: yuripv Date: Sat Oct 27 23:31:42 2018 New Revision: 339827 URL: https://svnweb.freebsd.org/changeset/base/339827 Log: localedef: define characters in "space" class also as "print", except for the known conflicts ("control" characters can't be "print"able). POSIX doesn't explicitly forbid this, and actually includes <space> character in "print".
