One way to get incomplete with status add is to interrupt a wc-to-wc
copy. That gives things like:

$ svn st wc
A + wc/X
! wc/X/B
! wc/X/f

But those have original_repos_relpath and the commit doesn't crash.

Is there some other way of getting incomplete with add? Perhaps an
interrupted merge?

The documentation for svn_wc__node_get_origin says that for an added
node (meaning not copied) the function returns NULL. This indicates
that callers are probably not going to crash if we return NULL for the
incomplete case:

svn diff ../src-1.7/subversion/libsvn_wc/node.c
Index: ../src-1.7/subversion/libsvn_wc/node.c

- *repos_relpath = svn_relpath_join(
+ if (!original_repos_relpath)
+ *repos_relpath = NULL;
+ else

I'd still like to be able to reproduce it.

Does this mean you cannot determine status in the same way you
determined status above?
