The original code was i18n-ready, but your code is not.  Please use
_() to wrap messages we display to the user.

In addition, I think "Run back to call of FOO" is not very clear.  I
wanted to suggest "Run to entry to FOO", but then I realized it would
be a lie: we do back up past the entry, to the instruction that
actually calls the function we are in, right?  Perhaps "Run back to
before the call to FOO" is better, even though it is wordier?

_() is missing around the message string (yes, I know it was missing
in the original code as well, but...).

_(), please.
