vc-revision-other-window problem

[Emanuele Giaquinta]

Hi,

in latest cvs vc-revision-other-window hangs in vc-ensure-vc-buffer
when called for the second time. The problem seems to be the following
code in vc-ensure-vc-buffer

    (while vc-parent-buffer
      (set-buffer vc-parent-buffer))

the first time it is fine because vc-parent-buffer is nil, but, since
vc-revision-other-window calls vc-find-revision which sets
vc-parent-buffer, the second time vc-parent-buffer will have a non nil
value. Hope the diagnosis is correct.
