@WnP thanks for the pull request!

I'm going to make some minor line comments in a moment but, as someone not super familiar with the changes between Python 2.7 and Python 3.3 // 3.4, I'd like a more detailed explanation of why these changes are necessary for forward-compatibility before I merge this pull request or evaluate it in detail.

Thanks!

for the second commit 1829ed8 this other answer on SO should help

Re. commit 88e2ecd

@WnP I'm testing on python 2.7.6, and I'm getting an error:

  File "stackit/stackit_core.py", line 210, in <module>
    main()
  File "stackit/stackit_core.py", line 199, in main
    term = getTerm(parser)
  File "stackit/stackit_core.py", line 135, in getTerm
    term += (output.splitlines()[-1] + bytes(" ", "ascii"))
TypeError: str() takes at most 1 argument (2 given)

And accoding to this SO thread that makes sense––bytes functions like string and does not take encoding as an argument.

Maybe add a condition that checks the python version? I can't merge this as is.
