Problem with liveupdate (zlib)

Hi,

I'm having some problems with liveupdate.

The first was to find some documentation about it. I only found it in
"man portfile" and it wasn't very precise (for example regarding the
regex syntax).

The second is even regex of some Portfiles in the repository are not
working. For example the zlib port (and others). It uses this regex:

"<B> *${name} (\\d+(?:\\.\\d+)*)</B>"

But it isn't working and I don't know why; it should match the text on
the webpage.
After I changed it to the following it worked:

"<B> *${name} (\[0-9\]+(?:\\.\[0-9\]+)*)</B>"

Is \d and such special characters allowed or not? I'm not sure about it.

Thanks for your help,
Simon

PS: I attached a patch for zlib to fix this problem. Also added another
patch to fix some whitespace and other minor issues in the zlib
Portfile. CCing one of the maintainers.
