> Why are wide punctuation any less punctuation than narrow punctuation?

Some wide punctuation characters are treated specially due to their
Word Break properties.  The details are in the comments where we
define text-mode-syntax-table, and in the Unicode Standard Annex 29
referenced from there.  It's just that there was a bug there.

> Sounds like a Euro-centered view of the world.

That's a nasty accusation which has no basis whatsoever.  Please don't
do that again here, ever.

> Why can't all punctuation be treated the same, narrow or wide?

It was a bug, plain and simple.  Now fixed on the master branch.
