Whoops! Technically, mod_dav_svn hasn't access to the knowledge required to
make this assertion. Who says a transaction's name can't start with a
dollar sign?

I'm still at odds with myself about this patch in general. HTTPv2 offers us
a chance to clean up and simplify our protocol, and before it even sees its
first release you want to add a bit of obfuscation and indirection required
solely by one commercial product? Come on. (If you know me at all, you
realize my antagonism is aimed not at said product, but at the proposed
protocol hack.) So I'm trying to convince myself that there's some general
utility to this change -- that somewhere, sometime, somebody else will thank
us for adding it.
