The input

    In[13]:=
    Series[-I q s - I p Sqrt[K1^2 - s^2], {s, 0, 1}]

gives

    Out[13]=
    -I Sqrt[K1^2] p + - I q s + O[s^2]

whereas

    In[14]:=
    Series[-I q s - I p Sqrt[K1^2 - s^2], {s, 0, 1}] // Normal

gives

    Out[14]=
    -I Sqrt[K1^2] p - I q s

What's that "+ -" doing in Out[13] ?  Is this normal?
