+ # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is
+ # evaluated as "\[ab\]". But that's not how TCL normally works; inside a
+ # double-quoted list item, "\[ab\]" is just a long way of representing
+ # "[ab]", because the backslashes will be removed by lindex.
+
+ # Unfortunately, there appears to be no easy way to duplicate the splitting
+ # that expect will do from within TCL. And many places make use of the
+ # "\[0-9\]" construct, so we need to support that; and some places make use
+ # of the "[func]" construct, so we need to support that too. In order to
+ # get this right we have to substitute quoted list elements differently
+ # from braced list elements.
+
+ # We do this roughly the same way that Expect does it. We have to use two
+ # lists, because if we leave unquoted newlines in the argument to uplevel
+ # they'll be treated as command separators, and if we escape newlines
+ # we mangle newlines inside of command blocks. This assumes that the
