It's probably worth making sure whether this is a shell issue or a
terminal issue.

Recall the line, then (regardless of it being mangled) go to the
start of it and enter "print ", then hit return.  If it's a terminal
issue the line you see will be correct.  It seems a bit unlikely that
that's the problem if it's associated with the option, though.

Are there any non-ASCII characters on the line that might be confusing
the algorithm (the option pre-dates handling of multibyte characters)?
