After that commit, an i-t-a entry can appear as a new file in "git diff-files". But the diff callback function in wt-status.c does not handle this case and produces incorrect status output. PS. The reader may notice that this patch adds a new xstrdup() but not a free(). Yes we leak memory (the same for head_path). But wt_status so far has been short lived, this leak should not matter in practice.
