description:
PR/45856: Bernhard "Burnhard" Riedel: Infinite loop on input. Sending
char 160 in the input to csh, lead it to an infinite loop, because tcsh tables
counted this as a space character, but the word logic switch does not. Change
that character tables, so that this does not count as a spacing character
anymore, by syncing the table with the one from tcsh.
