`d` is a mapping of shorthands to style names (a single style may
have multiple shorthands, in particular the shorthands `None`,
`"None"`, `"none"` and `""` are synonyms); `init` is one shorthand
of the initial style.

This function returns an list suitable for initializing a
FormLayout combobox, namely `[initial_name, (shorthand,
style_name), (shorthand, style_name), ...]`.
