[docs] [issue35110] Fix more spaces around hyphens and dashes

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

The following PR fixes several common errors in reStructuredText formatting.

* When the line is broken after or before a hyphen or dash, a space will be inserted after or before a hyphen or dash in the rendered text. This is not always appropriate. It is a common error when use old blurb (was blurb with the fix released?), but can be introduced also manually.

* Backslash followed by a space is used as a separator after a mark up, which doesn't insert a space. But when the line was broken on this space, this is not always work.

Fixed also other similar errors.
