printing special characters #724

Hi Team!

Recently I've noticed that it's impossible to print string containing "\t" character using bpython and print function (I have 0.17 on python 3.6.3 on Fedora 27 system).
Please find below simple test case:

python interpreter:

>>> print("aaa\tbbb\tccc")
aaa	bbb	ccc
>>> 

bpython:

>>> print("aaa\tbbb\tccc")

>>> 

So I guess that '\t' prevents string from being properly displayed. For example - '\n' works correctly:

python interpreter:

>>> print("aaa\nbbb\nccc")
aaa
bbb
ccc
>>> 

bpython:

>>> print("aaa\nbbb\nccc")
aaa
bbb
ccc
>>>

Have I missed something or it can be considered as a bug? Would you please take a look at it?

Best regards and thanks a lot for your glorious work on bpython!
