Ah, yes. Thanks for pointing that out. That's not what we want.

The concept of having the binary know the `svnversion` info of the

That wouldn't do what we want either. If you build from a tarball,
it'll bake "Unversioned directory" into the binaries. Also it would
mean that you must have svn installed in order to build svn,
regardless whether the sources were obtained from distribution tarball
or otherwise.

So... I guess what we're doing now makes sense.

Oh well, it was a nice thought.
