That's a separate issue.  Related to whether or not we should
take the display-table into account.

When would you do that and why (considering that we're specifically
talking about the global standard-syntax-table) ?

Really ?  I think this very much depends on the answer to the
previous question.

We really just need a table somewhere that tells us what is whitespace
and what isn't.  Currently I think there are two such tables, one is
the standard-syntax-table, the other is the ` ' category.  Actually,
I [:space:] and [:blank:] are two more, but [:space:] relies on the
buffer-local syntax-table (i.e. not good, although it's not that bad
since it only uses it for non-ASCII chars, IIRC) and [:blank:] only
matches ASCII chars (i.e. not good either).
