"Return the last preceding position at toplevel.
\"At toplevel\" means that it is outside of any syntactic entity:
outside of any parentheses, or comments, or strings.
Returns nil iff PPSS itself corresponds to a toplevel position."
"Get the latest syntactically outermost position found in a syntactic scan.
PPSS is a scan state, as returned by `partial-parse-sexp' or `syntax-ppss'.
An \"outermost position\" means one that it is outside of any syntactic entity:
outside of any parentheses, comments, or strings encountered in the scan.
If no such position is recorded in PPSS (because the end of the scan was
itself at the outermost level), return nil."
