Previously we would (also) search the default user data directory
for a defaults file, even if a different user data directory
was specified using `--data-dir`. This was a mistake; if
`--data-dir` is used, the default user data directory should
not be searched.
If the XDG data directory is not defined (e.g. because
it's not supported in the OS or HOME isn't defined), we
return the empty string instead of raising an exception.
Closes#7842.
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.

Closes#7506.
This also allows us to get rid of some special casing
on definition lists that ensured that options in code
spans would be boldface. (If this change is ever reverted,
we'll need that again.)
MathJax expect the config comes before loading the MathJax script.
This change of order allows one to config MathJax via header-includes,
which loads before the MathJax script.
This potentially is a breaking change.
However, the only kind math supported by pandoc that is configurable
seems to be katex, and according to src/Text/Pandoc/Writers/HTML.hs
the way it is configured is hard-coded (katex doesn't seem to offer
MathJax style config that is independent of loading katex.)
So it seems it is safe to change this order without breaking
others' documents.

with numerical styles that use superscripts (e.g.
american-medical-association.csl), as well as with
note styles. The default setting of `notes-after-punctuation`
is true for note styles and false otherwise.
This restores a behavior of pandoc-citeproc that wasn't properly
carried over to Citeproc.
Closes#7826.
