Fix section-from-path > 1
When having found the first path separator occurrence at position i, we
invoked strchr() on the same position i in subsequent iterations
resulting in the same path separator being returned by strchr() over and
over again. Increase the position by one to skip the occurrence that has
just been found and advance to the next separator.
