[Python-modules-team] Bug#843793: "ipython -c" fails when there are spaces in commands

[Younes Khoudli]

Package: ipython
Version: 5.1.0-2
Package: ipython3
Version: 5.1.0-2

Expected behaviour :

$ ipython -c 'print 42'
42
$ ipython3 -c 'print ( 42 ) '
42
$ ipython3 -c 'print(42)'
42

Actual behaviour:

$ ipython -c 'print 42'

$ ipython3 -c 'print ( 42 ) '
Out[1]: <function print>
$ ipython3 -c 'print(42)'
42

Seems like the wrapper scripts /usr/bin/ipython and /usr/bin/ipython3
don't quote their arguments when calling ipython.

Suggested patch:
