Are you always printing 'C', or
only printing 'C' if the file contents really are in conflict?
I'm pretty sure it's the latter, but I just want to be sure.

On a related note, in the reverse situation, if the file contents are
identical,
-svn merge prints 'A', but
-svn status prints nothing, because the contents are
unchanged...
I'm going to go out on a limb and say that should be fixed also.
However, by doing either one, we lose the ability to detect ancestry
changes during a merge. Seach each file object/evil_twin has a
different ancestry and history, Someone(tm) may want to choose which
object to keep. Without the 'A' from the 'svn merge' output, they lose
the ability to detect these cases. Personally, I'm happy that svn
auto-magically resolves evil twins in a common sense way (after 7 years
of ClearCase and trying to explain evil twins to users), but there's a
part of me that wonders about potential ancestry/merge issues down the
road.
