Regular expression module updated to do unicode character sets.

Most of the changes are in the area of representing sets.

Also, a bug was found in the compilation of regex character sets:
ranges straddling two adjacent blocks of 32 characters were
not being added to the character set. However, ranges falling
within a single 32 block, or spanning three or more such blocks,
worked properly. This bug is not tickled by common ranges
such as A-Z, or 0-9, which land within a 32 block.
