"+" command line parameters make sense
So here's a brief explanation of what this does.
If you had
+add cam_dist 200 before, that'd evaluate to
add "cam_dist 200". Obviously that's useless, so the new behavior has it evaluate to
add "cam_dist" "200". If you really want to have spaces in the second argument, just use
+add "cam_dist 200". :VVV
