That's a real shame.

I *think* the reason for this is that PHP 4.3.3 started using a newer
version of PCRE, and it is PCRE that added improved support recursive
patterns and sub-patterns. I could be wrong, though, and I'm too lazy,
er, busy, to look it up.

But I also think Michel's earlier analysis is correct: a simple pattern
that looks 6 levels deep for nested brackets ought to be enough for
99.999 percent of the cases. So far as I know, no one has yet complained
about this limitation in the current PHP code.
