It seems this patch breaks interactive conflict resolve:
With trunk I get the following to 'svn resolve' on binary file:
[[[
Merge conflict discovered in binary file 'A_COPY\theta'.
Select: (p) postpone,
        (r) accept binary file as it appears in the working copy,
        (tf) accept incoming version of binary file: h

  (p) - skip this conflict and leave it unresolved [postpone]
  (tf) - accept incoming version of binary file [theirs-full]
  (r) - accept binary file as it appears in the working copy [working]
  (q) - postpone all remaining conflicts
]]]

But with patch I get the following:
[[[
Merge conflict discovered in binary file 'A_COPY\theta'.
Select: (p) postpone,
        (r) accept binary file as it appears in the working copy,
        (tf) accept incoming version of binary file: h

  (p) - skip this conflict and leave it unresolved [postpone]
  (tf) - accept incoming version of binary file [theirs-full]
  (mf) - accept binary file as it appears in the working copy [mine-full]
  (r) - accept binary file as it appears in the working copy [working]
  (q) - postpone all remaining conflicts
]]]

I think it's confusing and we should not offer the same option twice.
