I don't think it's a good idea to store everything in LF in the
repository. Unlike Subversion, you cannot expect all interactions to
take place through the "eol-filter" we're implementing. Letting people
checkout a useful unfiltered clone would be possible if we know the
repository native format and convert back to that.

Anyway, it's a minor detail. More importantly, I've posted a simple,
rough extension that does this here:

I figured it would be better to discuss the design and implementation on
mercurial-devel since there are more Mercurial hackers there. I've CC'ed
a bunch of people from this thread to "seed" the discussion -- the rest
of you on python-devel are hereby invited to join :-)
