[issue39949] truncating match in regular expression match objects repr

[Quentin Wenger]

Quentin Wenger <wenger.quentin at bluewin.ch> added the comment:

And ascii escapes should also not be forgotten.

```
>>> re.match(b".*", b"\t")
<re.Match object; span=(0, 1), match=b'\t'>
>>> re.match(".*", "\t")
<re.Match object; span=(0, 1), match='\t'>
```
