[PATCH] vcs_info svn: Use the revision of cwd

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

Previously, the value of the wc root would be used.  In Subversion,
it makes more sense to use the revision of cwd, since all commands
(e.g., 'svn ci', 'svnversion') operate only on cwd and below, not on
wcroot and below.
---
This could happen if the working copy is checked out from trunk's
parent, or simply if one works on a single module and runs a few
updates/commits within that module's directory within the project.
