Fix [f1253530cdd83e66]: tcl_wordchars and tcl_nonwordchars are unknown at startup.
For trunk this will not be the complete story, but for core-8-6-branch and core-8-5-branch it will at least make tcl_wordchars and tcl_nonwordchars function as documented. That's the least polish we should do.
See: [https://groups.google.com/forum/#!topic/comp.lang.tcl/ZZ_WwfQdmoE].
People like Eric Brunel, who want the most logical behavior for any Tcl release can simply do:
set ::tcl_wordchars {\w}
set ::tcl_nonwordchars {\W}
