Calling `k` breaks `cd -`

[StreakyCobra]

Hi,

Thanks for your plugin, it's amazing.

I noticed a small bug annoying for people having the habit of using cd -. It is used to switch back to the previous directory. Your function is using some cd that are not done in a subshell – not within (...) or $(...) – and because of this the shell keep trace of all visited folders within the function.

To reproduce:

1. Preparation

   mkdir -p ~/TEMPFOLDER
   cd ~/TEMPFOLDER
   mkdir AAA BBB

2. Normal case

   cd ~/TEMPFOLDER
   cd AAA
   cd -  # Go back to TEMPFOLDER
   cd -  # Go back to AAA
   cd -  # Go back to TEMPFOLDER
   cd -  # Go back to AAA
   # Etc...

3. Wrong case

   cd ~/TEMPFOLDER
   cd AAA
   cd -  # Go back to TEMPFOLDER -> OK
   k
   cd -  # Go back to BBB -> not what i want...

I tried to look for correcting it, but the construction of the code doing the cd doesn't allow an easy fix, at least up to my knowledge. I can contribute if needed but before taking time on it I decided to open this issue to discuss the best way to solve it.

@StreakyCobra This should be fixed by a483c98c22870001fb2ad6dfb460a155641982ea

Hum it doesn't seems to solve the problem. But it's a minor one, I can deal with it :-)
