bpo-35133: Fix mistakes when concatenate string literals on different lines. (GH-10284)


Two kind of mistakes:

1. Missed space. After concatenating there is no space between words.

2. Missed comma. Causes unintentional concatenating in a list of strings.
(cherry picked from commit 34fd4c20198dea6ab2fe8dc6d32d744d9bde868d)
