Why can't Freelancer stand space in names?

[aerelm]

One of the simplest reasons is conflict with FLHook commands where parameters are separated by space.

/givecash Joe_Louis 100,000
/givecash*Space*<Charname>*Space*<Amount>
Or a better example,
/pm Joe_Louis Hi, don't forget to send me the movecodes for that char.
/pm*Space*<Charname>*Space*<PM Text>

Sure, humans can easily see the difference and know which is what, but a preset command? How should it know where the char name ends and the next parameter starts if there was to be an space or two in the name?

Although I don't know if it's a game engine limitation or can be hardcoded into the game, but it does make sense and seems to make writing FLHook commands much easier and less buggy, so I'm all fine with using . and - in my char names.
