[ZPT] TAL spec incorrect?

[Florent Guillaume]

Interesting. I didn't know that.

What happens is that if there is only whitespace between the start of
the line and the tag, it gets repeated too (with a newline).

This part of the code in TALGenerator does that:

        if repeat:
            # Hack to include preceding whitespace in the loop program
            repeatWhitespace = self.unEmitNewlineWhitespace()

I can see that it is useful but it's a gotcha in some cases...
