Lightroom Classic's keyword list files (Metadata ▸ Import / Export
Keywords): a keyword a line, those inside it one tab further in, a
synonym in braces on a line of its own under its keyword, a keyword
left out of export in square brackets.
- `Catalog::keyword_list_text` writes the whole tree that way, by name.
- `keywords::parse_keyword_list` reads one: Windows line ends, a
byte-order mark and blank lines are fine; a line it can't read (two
levels down at once, a synonym of nothing, a "|" in a name, nesting
past 64 levels: a file is input) is an error naming its line.
- `Catalog::import_keywords_ops` adds the keywords the library doesn't
have, with the file's attributes and in the library's spelling of
the levels it has; those it has keep their attributes and gain the
file's synonyms. One undo step.
