used to test a sed which (erroneously) evaluates this at translation
time rather than at execution time, the bugged sed is put into an
infinite loop. This mode of failure seems excessive. Such a failing
sed is the Free Software Foundation's sed 3.02.
The specific test was also not being executed for the BSD sed.
Both problems are now fixed.
