I ended up pushing #2 as a fix. It just seems nicer to make sure that
the new command gets a completely different copy of the List in all
cases.  That seems likely to reduce the chances of any future bugs
that might be caused if we ever add future code which modifies the
input list.

The fix will appear in 15.3

Thanks again for reporting this.
