patch for vc-svn.el

[Tom Tromey <tromey@redhat.com>]

I tried vc-dir on an svn-controlled directory and got:

  file-name-absolute-p(nil)
  cd(nil)
  vc-svn-registered("ChangeLog")
  apply(vc-svn-registered "ChangeLog")
  vc-call-backend(SVN registered "ChangeLog")
  #[(b) "\302^H\303     #\205^T^@\304   \305^H#\205^T^@\306\307\310\"\207" [b f\
ile vc-call-backend registered vc-file-setprop vc-backend throw found t] 4](SVN\
)
  mapc(#[(b) "\302^H\303        #\205^T^@\304   \305^H#\205^T^@\306\307\310\"\2\

This patch fixed it for me.
