Remove bogus split into lines inside a single comment block
Remove bogus split into lines inside a single comment block

We had wrongly assumed that the comment blocks inside paragraphs
correspond to the different lines, but an expression such as

    `<branchname>@{upstream}`

makes clang return each symbol in its own block. Adding newlines between
each of them makes us render bad data.
