OK..
After fresh restart, v2.13 doesn't respond to commands..
But, after pressing SPACE.. there was no visible action whatsoever, but LibreCAD is now accepting majority of commands listed on manual page (
https://wiki.librecad.org/index.php?title=Commands_and_tools_-_using_the_command_line).
No big deal, but I hope this will be fixed in new release (btw, when it is planned?) :-)
