Added using the following sed scripts:
- For command-ref/opt-common.md:
s~- `(--?)([^`]+)`~- [`\1\2`]{#opt-\2}~g
- For expressions/builtin-constants.md:
s~- `(builtins\.?)([^`]+)`~- [`\1\2`]{#builtins-\2}~g
- For expressions/advanced-attributes.md
s~^ - `([^`]+)`~ - [`\1`]{#adv-attr-\1}~g
and manually adjusted outputHashAlgo & outputHashMode.
- For glossary.md
s~^ - (`([^`]+)`|(.+)) ?\\~ - [\1]{#gloss-\2\3}\\~g;
s~(gloss-\w+) ~\1-~g
and manually adjusted anchors for Nix expression, user environment, NAR, ∅ and ε.
- For command-ref/env-common.md
s~^ - `([^`]+)`~ - [`\1`]{#env-\1}~g'
They are equivalent according to
<https://spec.commonmark.org/0.29/#hard-line-breaks>,
and the trailing spaces tend to be a pain (because the make git
complain, editors tend to want to remove them − the `.editorconfig`
actually specifies that − etc..).
