609 # TCL/EXPECT WART ALERT
610 # Expect does something very strange when it receives a single braced
611 # argument. It splits it along word separators and performs substitutions.
612 # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is
613 # evaluated as "\[ab\]". But that's not how TCL normally works; inside a
614 # double-quoted list item, "\[ab\]" is just a long way of representing
615 # "[ab]", because the backslashes will be removed by lindex.
617 # Unfortunately, there appears to be no easy way to duplicate the splitting
618 # that expect will do from within TCL. And many places make use of the
619 # "\[0-9\]" construct, so we need to support that; and some places make use
620 # of the "[func]" construct, so we need to support that too. In order to
621 # get this right we have to substitute quoted list elements differently
622 # from braced list elements.
624 # We do this roughly the same way that Expect does it. We have to use two
625 # lists, because if we leave unquoted newlines in the argument to uplevel
626 # they'll be treated as command separators, and if we escape newlines
627 # we mangle newlines inside of command blocks. This assumes that the

3278 # . It works with MI, and it also works when gdb is not running.

3283 # $srcdir/$subdir to be compatible with the old implementation.
