[issue2126] Cannot clone massively multiheaded repositories over HTTP

[Dan Villiom Podlaski Christiansen]

New submission from Dan Villiom Podlaski Christiansen <danchr at gmail.com>:

Repositories with hundreds of heads cannot be cloned over HTTP. This has been seen in 
the wild with <hg.python.org/cpython> — which supposedly has more than 400 heads. I've 
created a dummy repository which reproduces this:

% hg clone http://bitbucket.org/danchr/polycephaly/
destination directory: polycephaly
requesting all changes
abort: HTTP Error 414: Request-URI Too Large
% hg clone ssh://hg@bitbucket.org/danchr/polycephaly/
destination directory: polycephaly
requesting all changes
adding changesets
adding manifests
adding file changes
added 1000 changesets with 1 changes to 1 files (+999 heads)
updating to branch default
1 files updated, 0 files merged, 0 files removed, 0 files unresolved

I've attached a bundle of the repository.
