Conditional: Do not use noReply() after running the command.

As the command already calls reply() or noReply(), calling noReply()
there had disastrous effects:

* if reply() was called, noReply() erases the argument
* if noReply() was called, calling noReply() a second time erases **the next argument** (because the current argument was already erased).

This was 'caused' by the change of behavior of noReply() in 543edccd41.
