[Cuis-dev] isSeparator

[Ezequiel Birman]

Lately I've started tinkering with text morphs and I was wondering about
UnicodeCodePoint > #isSeparator. I needed to (in)validate non-drawable
codepoints including control sequences, but the current implementation
doesn't include the codepoints for thin space, hair space, em space, etc.
is it on purpose? For what is worth I gathered all the non-drawable
codepoints (maybe some are still missing):

^ `#(32 9 10 13 12 160 8192 8193 8194 8195 8196 8197 8198 8199 8200 8201
8202 8203 8239 8287 12288)` statePointsTo: value

Also, I learned that there is one separator that *is* drawable: The Ogham
space mark. Probably, it should be included too, unless I am
misunderstanding the semantics of isSeparator.

I should have added comments describing the codepoint, will do asap.
