Subject: [PATCH] optionally not store inputcommand into command history

  inputcommand <init> <command> <prompt> <nopersist>

    Opens a custom console buffer with custom prompt, initial buffer text
    and execution script (which gets the input buffer content in alias
    cmdbuf). If nopersist is not zero, the command will not be stored in
    console history.
