gitk: Do not mistake unchanged lines for submodule changes

Unchanged lines are prefixed with a white-space, thus unchanged lines
starting with either " <" or " >" are mistaken for submodule changes.
Check if a line starts with either "  <" or "  >" only if we are listing
the changes of a submodule.
