Don't silently drop leading numbers and unusual characters at the
start of a command - for example, don't interpret '99M88' as 'M88'.
Don't silently drop spaces in a command - for example, don't interpret
"M 101" as the command "M101". Doing so will cause other parts of the
code (such as get_raw_command_parameters() ) to not work properly.
