Hi Andy,

This very likely is related to or caused by the changed parsing of
$((…)) in 5.0.8.

I remember that there were also $((…)) related fixes after 5.0.8, but
I need to check the details.

Likely, yes. But I can reproduce the issue here, too, with the same
configuration as on 5.0.7.

Workaround for now: Use Ctrl-X * instead of Tab. This still seems to
work.
