Now it's getting confusing. "Extra" space - compared to what?
The correct format of this special split is
split ' ', EXPR
i.e. two quote characters with _one_ space character between them.
That's what I had initially suggested. When you said you added an extra
space, you were getting two quote characters with _two_ space characters
between them. As John pointed out, the latter is no longer the special
case format, and is simply interpreted by Perl as
split / /, EXPR
Maybe, in order to reduce the confusion, could you post the complete
final version of your code?
