localization issue with -q option

Are you aware of the fact that the argument to the -q option
is internationalized? I.e. with my German locale settings I
have to type "oggenc -q 4,99" instead of "oggenc -q 4.99" if
I want to use a quality setting with a decimal point.

Well, this isn´t a problem in itself. However, the English
documentation is very confusing for German users (or users
with a similar locale). There should at least be a warning for
users of other locales that they may have to use "," instead
of "." depending on their locale.

I could also imagine that this can break some not locale-aware
programs which launch an oggenc process and try to set the
quality without setting a private "C" locale environment for
the oggenc process first.

Unfortunately, I don't know the best practices concerning
command line argument localization. I hope you guys make
a good decision.
