s/ought/should/

I know we don't use it very much, but I persist to say that it would be
better if we did so.=20

I now remember why it's not used in the Po.pm module (but there is no excuse
why it's not used in Sgml.pm and such). We have to preserve the space at the
end of the line here, and all wrapping modules keep eating it. They change:
 "toto tutu toto tutu "
to
 "toto tutu"
 "toto tutu"
But to preserve the po file semantic, we need:
 "toto tutu "
 "toto tutu "

Explaining why we keep using a wrapping algorithm which is known to be
broken for some languages. I wanted for ages to fill a wishlist bug report
asking Text::WrapI18N to provide an "space preservation" option. But I
didn't yet, my bad. I'll try to do so soon.

Now, about using it through a wrapper, I think this is a good idea. The
wrapper could even be smart enough to detect that you're using thai (or
another language making this module mandatory) encoding (or chars, if UTF8),
you're going into problem and emit a warning.

Sure. Once again, I was unclear, sorry. I'd love to see disapear, but won't
do anything for this myself in the next months. I just wanted to note that
the only dependencies Francois were ok with are the ones I'd like the most
to kill :)

Bye, Mt.
