[New-bugs-announce] [issue24727] Expand readline module

[Barney Stratford]

New submission from Barney Stratford:

I have a use case where a daemon thread needs to write periodic updates to sys.stdout. I'd prefer it not to print in the middle of a command being typed. In order to achieve this, I have added to the readline module. There is now a function to determine whether we are reading a line, and one to call rl_forced_update_display. These functions enable me to say (in the daemon thread):

def describe (indicator):
    if readline.reading_line ():
        print ()
        print (indicator.description)
        readline.forced_update_display ()
    else:
        print (indicator.description)


I have read PEP7, and have made patchtest on my patch.
