Out of date wiki - compress extension

[Vladimir Marek]

Hi,

It seems that http://mercurial.selenic.com/wiki/CompressExtension is a
bit out of date. The link to
http://selenic.com/hg/file/tip/contrib/compress.py is no longer valid.
Looking at the file's history, it was removed by:

changeset:   12719:215ba8791f10

description:
        parentdelta: compress.py extension is no longer necessary

        Using `hg --config format.parentdelta=True clone --pull src dst` is equivalent.

removed:
   contrib/compress.py



Info similar to the commits description would be helpful on the wiki
too.

Thank you!
