You're right.  I probably thought this is defined since v2.72a,
thus not needed.

This is much better, I'll merge it as this (unless anybody objects).

I'm not sure if v2.72a (alpha?) is shipped to any distro. v2.72 haven't been
released yet.

The reason to update the comment was
1) don't confuse with very old version (it's still needed)
2) notify users once v2.72 is released and shipped in case of problems.

Kind regards,
Petr
