Yes, if the spaces were missing from those two lines, this would have the same output ("jurt annther..."), but the code was not hand edited, it was copied and pasted, and produced the expected results in some cases but not in others, so I'm certain the spaces were not missing.

Furthermore, all builds of Perl 5.6.0 that we tested printed the expected output using the same code.

Update:
It turns out that the right end whitespace on the first two lines assigned to $_ was truncated, evidently by a copy and paste on one of the boxes.

I will never again allow myself to be sidetracked.
