That "backspace=indent,eol,start" part looked interesting, while it's
working perfectly in gvim and vim, cream still says the same thing
("E319: ...."). There is a slight delay between the keypress and the
error message, almost as if cream was executing some script/code
Is it possible to turn some debug/info messages on to console or to file?
This might be helpful:
Nothing jumped out at me as being obviously broken in the version output
