Several types of \bar are not engraved

[Tarik]

Brand new LilyPond user here. I tried compiling a couple of .ly scores by
other authors, and repeat bars were missing. So I make the tinyexample below
-- entirely derived from the LilyPond documentation of the \bar command --
and find that only 8 of the expected 14 types of \bar are engraved. Where I
have indicated "nothing engraved," there is nothing at all, not even an
ordinary measure bar.

Any insight into what is missing will be much appreciated.
