This is great. Only one thing I'm missing what is the reason to use
repository root and encode path parameter in query args? From my point
of it's much better to work on target URL, without knowledge of
repository root. I mean:
    GET /repos/trunk/foo.c?cmd=get-file&r=23
instead of
    GET /repos?cmd=get-file&r=23&path=/trunk/foo.c

Because resolving repository root takes additional workaround unless
we have working copy.

Another bikeshed comment: I propose use 'svn-cmd' instead of 'cmd' to
be able serve several services (Subversion web access for example) on
the same URL.
