Similar answer. When Subversion stores each revision in the
repository, it often will only store the diff. So to record this, it
would have to internally "svn cat" the whole file to get a file size.
On a large commit, this could be very expensive. I'm not sure that the
commit process could handle calculating it on the client end &
transmitting it as part of the commit; there may be some huge holes in
that idea which I can't think of offhand.
