all time -- the quoted string.

48d5cceb8f Add more tests of seq_parser and or_parser, to cover all the permutations of 
different parsers that they might use.

Fixes #126.

87b50154cf Fix incorrect attribute returned by a rule in some cases. The problem was 
that the changes to support recursive rules made all rules use the out-arg
overload of parse_rule.  This is wrong.  Now, rules use the
attribute-returning overload unless asked explicitly to use the out-arg one,
*or* if the rule is being invoked recursively, and we are in an iteration
after the 0th.

Fixes #125.

27506af2f3 Constrain parse() overloads that take an out-attribute Attr & -- but no 
skipper -- so that Attr is not derived from a specialization of
parser_interface.  This prevents this from being the best overload when using
a mutable skipper, and producing lots of diagnostics that say the skipper
(which would be mistakenly bound to Attr &) is not assignable from whatever
the attribute type is.

Fixes #105.

ab4d708c30 Set the out-param to Attr() on parse failure (for the overloads taking an 
out-param), making alls to parse() consistent with calls to parsers. Parsers
clear the attribute on failure. Add a section to rationale on why this is the
right choice.
