It's a fair cop.  That was indeed broken.  The fix is to postpone
unsetting C-L until after the first get_brigade from upstream,
where it's required.

Fixed in r563133

I've also hacked up a draft for another input filter that'll
re-insert content-length if it's required - e.g. proxying to
a 1.0 server.  That's potentially expensive, because it means
buffering the input in order to count it, so the filter takes
care to run only when strictly necessary.  Happy to include
it in the core distribution.

Yep.  That wants another patch, which I'll be happy to do.
