Dunno, I suppose sometimes maybe it is reasonable to allow the details
to be tweaked; it's "consistency of feel" which is the goal, which may
not always entail literal consistency....

For instance:  is a single-quote part of a word?

In text-mode, it is, and that makes some sense, because single-quotes
are mostly followed by a single letter to form a contracted thingie.
Having word commands stop at the single-letter boundary in such cases
would be pretty annoying and not particularly useful, and generally
wouldn't feel "right" (even though there's a visual boundary).

However in some programming language mode that uses single-quotes like
Ada does, as an operator, you really want them to be punctuation,
because they are used to separate independent pieces that are thought of
as independent.
