feature request : onoff option to when c-c make a space before the displayed ^C

[#!microsuxx]

i had many times i control-C and it ruined the command copypaste
i only had such experience , no good , by no space between when ^C is
printed by c-c by the shell ..

so i suggested an on off option to make it print a space before
or other option for other mod , but i dunno
so only this one space before ^C opt
