Issue Description:
`ArgumentParser` parses short option and option-argument without delimiting space as a single (likely unrecognised) option.
For example, if an option is added to the parser with a short name of `-n`, `ArgumentParser` parses `-n 2` as the “n” option with “2” as its option-argument.
But it parses `-n2` as the unknown option `n2`.
Where long options are prefixed with `--`, it is common for CLI to treat `-n2` and `-n 2` identically.
This probably also implies `ArgumentParser` doesn’t handle adjoining flags (e.g. parsing `-abc` identically to `-a -b -c`) — but I haven’t tested this.
