So putting control characters aside, and space wich is not part of an unquoted
word,
they are just one of "!\"#$%&'()+,-./:;<=>?@[\\]^`{|}~",
I'm looking in the wrong file, lex.c? If not, may be that explicit list would
be nice in rio(1).
I'm going to study the code and shut up my mouth.
>> characters of the same type (c>' ' &&
>> !strchr("!\"#$%&'()+,-./:;<=>?@[\\]^`{|}~", c)) should be skipped too,
