Mhmm, more tests show that for `@code{foo--bar}` there is no
`@discretionary` after the two hyphens.  Is this intentional?

Additionally, I wonder whether the same logic should be applied to
`_`.  If you want to document, say, C prepocessor symbols, you will
have tokens like `_foo` or `__foo_bar`, and `texinfo.tex` happily
inserts `@discretionary` after all of those underline characters.
