Junio C Hamano cc908b82a4 diffstat rename squashing fix. ...

When renaming leading/a/filename to leading/b/filename (and
"filename" is sufficiently long), we tried to squash the rename
to "leading/{a => b}/filename".  However, when "/a" or "/b" part
is empty, we underflowed and tried to print a substring of
length -1.
