Import patch from Roman Imankulov:

"sdcv" does not set up `rl_readline_name' variable which can be extremely useful for the writing the .inputrc file. Additionally sdcv does not use readline in the "Your choice [-1 to abort]" dialog. This patch fix both these issues, readline_name is set up to "sdcv".
This trick allows me to add into the .inputrc
$if sdcv
"\e\e": "-1\n"
$endif
and type double-escape in the "Your choice" dialog instead of pretty annoying "-1".
