Hi Sam,

Thanks for your bug report.

The patch is pretty obviously correct; I will apply it.  It would be
nice to have a test case to ensure the bug doesn't reappear.  Can you
describe how to reproduce this easily (I'm not running w32 ATM)?  Of
course a patch to the tests/execute-mode.at would be great too, but we
can do that.  Bonus points for providing a ChangeLog entry.  Mind if I
put you in THANKS?

It looks to me there is a plus sign missing in that patch, but it is
less portable to old shells.

Well that's nice to hear!
