#   $ svn mv a b
#   $ svn ci
# and a later revision that modifies b.  We then try a fresh checkout.  If
# the server happens to send us 'b' first, then when it later gets 'c'
# (with a copyfrom of 'b') it might try to use the 'b' in the wc as the
# copyfrom base.  This is wrong, because 'b' was changed later; however,
# due to a bug, the setting of svn:entry:committed-rev on 'b' is not being
# properly seen by the client, and it chooses the wrong base.  Corruption!
#
# Note that because this test depends on the order that the server sends
# changes, it is very fragile; even changing the file names can avoid
# triggering the bug.
