The aim here (see #9020) is to produce more standard and more
portable man pages. To that end:
- We revert the fanciness introduced in #7506, which employs a
custom font name V and a macro that makes this act like boldface
in a terminal and monospace in other formats. Unfortunately,
this code uses a mechanism that is not portable (and does not
work in mandoc).
- Instead of using V for inline code, we simply use CR.
Note that `\f[CR]` is emitted instead of plain `\f[C]`,
because there is no C font in man. (This produces warnings
in recent versions of groff.)
- For code blocks, we now use the `.EX` and `.EE` macros,
together with `.IP` for spacing and indentation. This gives
more standard code that can be better interpreted e.g. by mandoc.
The V font is defined conditionally, so that it renders
like CB in output formats that support that, and like B
in those that don't (e.g. the terminal).
We could just redefine C, but this would affect code
blocks, too, and putting them all in boldface looks ugly,
I think.
Possible drawback: fragments created by pandoc's man
writer will presuppose a nonstandard V font.
Closes#7506.
