This is a first draft with three main limitations:
- it is language agnostic, so it does not know about field names
- it is not able to parse comments
- it does not break long lines
The formatting rules are pretty simple:
- lists composed only of atoms, quoted strings, templates, and
singletons are displayed on a single line
- other lists are displayed with a line break after each element
- an empty line is inserted between toplevel stanzas
The CLI is pretty light: it can either read a file or standard input,
and fix a file in place. In addition, the command is named
`unstable-fmt` for now, until some guarantees are given.
Closes#940
