Filing an issue so this won't get lost:
A new field in the svn_client_status_t struct which has the size of the
file in the working copy, or -1 if not known. For most file this
information should be available automatically since svn_client_status
has to do a stat() call on the file anyway to determine its file time or
at least when comparing the size to its BASE. So if that information is
available, I'd like to reuse that info and not have to do a stat() call
again later, basically doubling the stat() calls and therefore hurting
the performance a lot.
