In Cwd, convert two regexps to explicit ranges, instead of using /i

Since change 56ca34cada940c7f moved the folding of ranges from runtime to
compile time, these VMS-only regexps would incur a startup cost penalty on
all platforms.

This also removes build-time warnings when Cwd is invoked before the Unicode
tables have been processed.
