Subject: [PATCH] Don't strip space from python completions

The returned completion deliberately includes a space after a word like

'import', which is always followed by more words.

* lisp/progmodes/python.el (python-shell-completion-native-get-completions):

Remove space from regular expression character class

I have only tested this on macOS. As far as I am aware, when the space character is present, it is present deliberately and it is appropriate to retain it, but I would appreciate feedback from python.el experts.

From emacs -Q:

M-x run-python

In the python comint buffer insert "from itertools imp" and hit tab.

You will see "imp" completed as "import" (no trailing space).

However, if you do this in ipython itself, you will see "imp" completed

as "import ". This (i.e. what ipython does) is the desired behavior

(because import is always followed by another word).
