Revision 63129 is not valid on case folding filesystems. In
particular, this horribly breaks using hg-svn to make a local mirror
of the Python repository:

>\Apps\HGsvn\hgimportsvn.exe -r 63120
http://svn.python.org/projects/python/trunk foo
>cd foo
>\apps\hgsvn\hgpullsvn
>hg log Lib\socketserver.py

summary:     [svn] Renamed SocketServer to 'socketserver'.

>hg up -r2
abort: case-folding collision between Lib/socketserver.py and
Lib/SocketServer.py

>hg up -rtip
abort: case-folding collision between Lib/socketserver.py and
Lib/SocketServer.py

The hg repository is now totally broken.

I'm not sure there is a fix for this, short of going back and manually
fixing the history (and I don't know if this is possible at all using
Subversion).

I know it's a rare situation, but can people PLEASE be careful not to
introduce case issues like this - they pollute history for ever (I
still hit problems with some of the case funkiness in svn from the
early 1990's!!!)

Bazaar seems to be OK (ish) with this - it picks just one version to show.
Paul.
