Four existing tests trigger the same error message:
* bad-type-int.err enum-int-member.err
Only because we neglect to parse numbers.
* escape-outside-string.err funny-char.err
These test stray '\' and ';'.
I guess a separate test covering bad literal names would be useful if we
actually do something different there.

What regular expression should the lexer consume for a literal name?
My patch consumes (true|false|null).
For what it's worth, qobject/json-{lexer,parser}.c consume [a-z]+, then
reject anything but true, false, null. Lexes false0 as two tokens
JSON_KEYWORD false and JSON_INTEGER 0. Can't find a context where the
parser accepts that pair. It rejects it with its usual garbage error
message "Invalid JSON syntax".
