I tried but it seems not to work.

Actually I did this wrong, I haven't thought this through.

Under gettext poison:
sed -e "1,/^Did you mean this/d" removes all lines, gives no output.
And then the one second, sed -e "/GETTEXT POISON/d", outputs "lgf" as
expected.

But running normally (without gettext poison):
1st sed outputs "lgf" as expected
And then second one output the entire 'actual' file, like if it were
cat, undoing the first sed.

I think the sed here is superfluous in the first place.
Should we remove it? If it weren't the case of gettext poison it was ok
to have sed there, but it makes the test fail under gettext poison.
