It does not run on C-c, but it does run in other cases, typically if you
just press Enter after reading the message that says “command failed,
press Enter”.

I don’t see how to address the C-c issue so we’ll have to live with it.

Longer-term we may have to find a different strategy than the
‘call-with-mnt-container’ trick, but that’s difficult.

Right; #60116 is related, and it’s not great but it’s not critical.
