commit patch from LP#1381965 and two testcases, one showing this is fixed,
another showing deeper problems (probably LP#1381993 “non-list contexts” or
the IFS_WS/IFS_IWS story, perhaps *all* IFS_WS (not just ternaries) really
should be IFS_IWS instead?)
erm yes, committed the wrong patch…
IFS_IWS, but doesn’t really change much…
better fix
first cut at LP#1381993 (probably incomplete) plus test coverage
also remove fbsd testsuite link, it’s gone during cvs→svn of theirs ☹
