Re: [Freefont-bugs] FreeMono affected by OS X 10.6 nested character references bug

[Steve White]

Hi, Mach,

If it's really just the two characters, I'm willing to fix it as a "courtesy".

Anyway, if such an odd thing as deep reference nesting happens in just
a couple of places out of so many thousand characters, there ought to
be a really good reason for it, and I'm not convinced that is the case
here.

For the cases of the multiple quotes, I reduced the nesting in the CVS
version of all faces of FreeFont.

Thanks for the heads-up.
