Make syntax changes explicit

For example, simple commands like lsp 0,":s/26,26,0;#ffffff`TEST",20,20 doesn't work, ThingsThatAreNoLongerLegal.txt is not clear enough to easily fix such a command.

The documentation of NScripter is very vague. The semantics of commands are inferred from usages, not taken from the documentation. It's quite possible there are things that work on NScripter/ONScripter (either by design or by accident) and don't work on ONSlaught.

Maybe NScripter's official documentation is clearer if you mention the translated one, I should take a look at it.
