- This commit modifies CommandParser to better track positional parameters
which previously used to go there for non-recognised options. Now using
relatively dump logic of just checking if first positional parameter starts
with '-' which indicates it's a candidate for a new `UnrecognisedOptionException`
which then would give user an error "Unrecognised option '--xxx'" for example.
