- Classic Mac line ends (a lone carriage return) are lines: a whole
file used to become one keyword holding them.
- Indenting with spaces is refused at its line: the levels are tabs,
and space-indented files (hand edits, editors that turn tabs into
spaces) used to come in flat without a word.
- Control characters in a name, and "|" in a synonym, are refused.
- A keyword repeated in another case keeps its first spelling for the
keywords inside it.
