Re: "path" during a commit walk

From: Greg Stein <gstein_at_lyra.org>

First off: we have *two* paths of interest during a commit walk:

1) the URL pointing at the repository
2) the filesystem path for local files

The RA library uses (1) to know where to commit the changes. But it needs
(2) to fetch properties stored on the local system.

I'm presuming that the commit process will begin at ".../down" rather than
".". In other words, we call RA->open with the repository URL at .../down.
And then call replace_root() there.

[ the alternative is to call RA->open with the URL corresponding to "." and
  then do a replace_dir all the way down to .../down; those are wasted
  replace_dirs, though. ]

In the above case, I cannot construct a filesystem path to pass to the WC to
fetch properties. I never saw "some", "dir", "way", or "down" in replace_dir
arguments. Therefore, I can't "telescope" a path which can be used from the
current-dir down to the appropriate file.

But even so, if the RA/DAV *knows* that it needs to call svn_wc_prop_get()
to get information about the [commit] walker resources, then we've tied the
two together too strongly. This was the point about the svn_resource stuff,
and passing that into the editor callbacks.
