Spacing is required because Python's arg parsing library treats "-1:3.123" in e.g. wheatley 123456789 --single "-1:3.123" as a set of short arguments (same as -.:123). However, inserting whitespace like in "-1: 3.123" means that argparse can't treat it as a set of short options.
An open question is whether it's worth actually explaining the problem in --help but I think the help is long enough already and in most cases this is simply unnecessary detail. It should probably be documented somewhere other than a commit message, though, but I'm not sure of the best place. @centreboard, thoughts?
