That one is new to me.  So a quoted or escaped space is no longer a word 
delimiter.  Yeah ... that's why in typeset, any naked space is a 
delimiter, even a dozen of them make no difference, they are 'just' 
delimiters.  Yup, this kind of thing won't catch me again.

Geez ... that's dicing with the law. I'm seeing:
'That'
then an escaped apostrophe, so literal,  then
's all, folks!"
... three ... dunno how to say it ... three words joined into one.
