James wrote it in Pascal. So it uses read() and readln(). If I
remember Pascal IO correctly, read() parses and returns the next bit
of input that matches the variable types passed in. So if you pass it
a number, it reads a number. I don't remember what it does with
strings. But yeah, it ignores line breaks (except as whitespace).
More specifically, I think (but I haven't tested) that LDraw will read
as many lines of data as it needs to complete a command, and any extra
characters after the last parameter are ignored.
