Hmm, that is interesting.  Said optimization was disabled in 10.6.1 (by
making it conditional on compat 11) and the rewritten for 10.6.3.  That
suggests it is a different thing happening.  Probably caused by the
rewrite of the glob expansion though.

I am a bit surprised why this would occur as AFAICT the splitting on
space happens during parsing, which I have left unchanged.

Can you provide an example of what worked before that now breaks.  If I
can get a minimal test case up and running, I can probably bisect the
code and figure out exactly where it breaks.

Thanks,
