bug#25753: 25.2; Python mode shell interaction not working 100%

[Carlos Pita]

Regarding my issue, short of resetting the entire inputrc config
somehow, one can workaround the problem by changing:

                  (comint-redirect-finished-regexp
                   "1__dummy_completion__[[:space:]]*\n")

to:
                  (comint-redirect-finished-regexp
                   "1__dummy_completion__.*\n")

This is in order to match outputs like:

    0__dummy_completion__ [0m [K  1__dummy_completion__ [0m [K

Given the fragility of all this, I think it's better not to be too
picky regarding the matching condition, which is selective enough
without enforcing spaces at the end. So I propose that minimal change.
