Simon Lydell 9ec427ba80 Fix #2516, #3560: Unicode space handling ...

It is possible to match only valid JavaScript identifiers with a really long
regex (like coco and CoffeeScriptRedux does), but CoffeeScript uses a much
simpler one, which allows a bit too much.

Quoting jashkenas/coffeescript#1718 #issuecomment-2152464 @jashkenas:

In short, CoffeeScript treats any non-ASCII character as part of an identifier.
However, unicode spaces should be excluded since having blank characters as part
of a _word_ is very confusing. This commit does so, while still keeping the
regex really simple.
