Tabs are considered to be a single whitespace character here.
But it's okay to give tabs their own markup rule:

    # lines beginning with tabs are always preformatted text
    Markup('^tab', '<^ ', '^\t', '<:pre,1>$0');

Lots of browsers have difficulty entering tabs into textareas, which
is why I haven't relied on this for anything I do.

No, I don't want it to look like we're setting a variable (even if that's
what we're doing) -- directives should indicate the result we're trying to
achieve, not how it's to be done.  (Because "how it's to be done" could
easily change at some point in the future.)

Thus we say (:notitle:), (:nofooter:), (:spacewikiwords:) and the like
without reference to the corresponding PHP variables or settings.

This might also be possible.  But notice that the (:wspre:) option
I discussed above already provides some of this capability:

    (:wspre:)
       this is preformatted text
    (:nowspre:)

I don't think we need two separate directives for this -- so perhaps
"wspre" is just "pre" and it allows a variety of arguments that
can determine how preformatted text is identified/rendered for
the page (at least until the next (:pre:) directive).
