WaitExten missing in Announcements

When a digit is selected in the 'Repeat' field then the generated code includes a

{noformat}
exten => s,n,Set(TIMEOUT(response)=3){noformat}

which is the right thing to do, u'know, give the user time to press that digit.

But you fail to also include

{noformat}
exten => s,n,WaitExten(,){noformat}

after the

{noformat}
exten => s,n(play),Background(custom/message|nm){noformat}

which results in

{noformat}

Note: When I added the WaitExten command the 'Auto fallthrough' did not occur.
