The word “special” in the title, in this case means anything else that a normal buffer (a file). Additionally make sure we reset the alternate window as well so we can keep using that as expected.
For details why this fix is needed, please see this issue ctrlpvim/ctrlp.vim#235 and the comments (mainly the last 5 or so) of this PR ctrlpvim/ctrlp.vim#303
Also please see Xuyuanp/nerdtree-git-plugin#63 as the related code was copied from there and they just merged the same fix as well. So this PR implements that same fix as users have reported the same issue when using this plugin as well.
