another email thread is ok, i suppose, but it feels like we've retread this
territory <exaggerated>a gazillion times and everything is always repeated and
nothing ever changes.</exaggerated>  i know these threads get archived (e.g.
the link above), but i think it might be prudent to document this issue in a
somewhat more readable, organized, and permanent form.

for instance, each of these four options could get their own page with a full
explanation, examples, patches (if they exist), arguments on behalf of the
option, and any relevant bugzilla links.  this would help to ensure clarity
and understanding on all parts.

the main page on the subject could contain a brief summary, links to the
above, and space for users/contributors/committers to indicate their
preference.  i believe this would help to generate a better feel for what peop
le want and what people despise.

we might also include some pages documenting alternatives and workarounds.

and actually, i took a few moments to get things started...
