set_input_transition -clock_fall requires value argument

[Chopper455]

Tcl procedure to parse arguments in set_input_transition treats -clock_fall as a key, not as a flag. Regardless of the fact that it isn't used later.

proc set_input_transition { args } { parse_key_args "set_input_transition" args keys {-clock -clock_fall} \ flags {-rise -fall -max -min}

I fixed it to report an error because it is not supported.
