Make %PHRASE_CHARDEF only apply to %chardef commands.
Make %PHRASE_CHARDEF only apply to %chardef commands.

I hope there'll be some better logic to decide this automatically in future.
Unfortunately now we can't do that because
 - Some CIN implementations adds useless comments because original XCIN ignores
   everything after space
 - Some CIN implementations do as our default behavior.
 - Some CIN implementations has revised table and do %PHRASE_CHARDEF by default.
