New issue 2718: pypy3.5 traceback when hitting backspace in repl
https://bitbucket.org/pypy/pypy/issues/2718/pypy35-traceback-when-hitting-backspace-in

Miro Hrončok:

In interactive prompt, when I remove a character via backspace, a traceback is scattered all around my terminal with the following:

```
Traceback (most recent call last):

    if '*' in m.group(2):

During handling of the above exception, another exception occurred:

```

Note that this only happens with a minimal setup in Fedora's build environment. where the tty is somehow limited and I cannot reproduce this on my normal environment. 



Adding `b` into `if b'*' in m.group(2)`  fixes the problem, will try to send a PR, but Bitbucket keeps saying it is forking the repo forever.
