[bug]: `defaults` in default YAML does not interpolate `${.}`

[gabyx]

Explain the problem.

The defaults: section does not interpolate ${.}, which it should according to documentation.
Probably the interpolation was forgotten in these paths.

general.yaml:

defaults: ${.}/general2.yaml

general2.yaml:

eol: lf

echo "asd" | pandoc --data-dir=. --defaults=general.yaml -f markdown -t markdown

pandoc: ${.}/general2.yaml: openBinaryFile: does not exist (No such file or directory)

Pandoc version?
2.18

Unless it's intentional that the ${} syntax is not supported in this context, this does indeed seem to be a bug?

This is also an issue for the to-field, which can be used to specify the writer.

The following defaults yml file fails to resolve the ${.}:

from: markdown
to: ${.}\writer.docx.lua

[edit] I imagine it might also fail for the from field. I don't have a reader handy so didn't check.

The way the architecture works currently, it is not trivial to add interpolation in defaults. I'll need to restructure things somehow to make that work. (Technical note: the issue is that the JSON/YAML parser doesn't have access to state.)

Adding interpolation to to and from should be straightforward; I'll do that.
