Requiring Tcl 8.1+ in order to obtain I18N is reasonable. Changing
tcltkgrass so that it will not run at all without Tcl 8.1+ isn't
reasonable.

Basically, it just means that the implementation method needs to allow
for the case where the "msgcat" package isn't available, e.g. by
providing a stub implementation.
