The "--sort" parameter of for-each-ref, etc, does not handle negation,
and instead returns an error to the parse-options code. But neither
piece of code prints anything for the user, which may leave them
confused:
$ git for-each-ref --no-sort
$ echo $?

As the comment in the callback function notes, this probably should
clear the list, which would make it consistent with other list-like
options (i.e., anything that uses OPT_STRING_LIST currently).
Unfortunately that's a bit tricky due to the way the ref-filter code
works. But in the meantime, let's at least make the error a little less
confusing:
- switch to using PARSE_OPT_NONEG in the option definition, which will
cause the options code to produce a useful message
- since this was cut-and-pasted to four different spots, let's define
a single OPT_REF_SORT() macro that we can use everywhere
- the callback can use BUG_ON_OPT_NEG() to make sure the correct flags
are used (incidentally, this also satisfies -Wunused-parameters,
since we're now looking at "unset")
- expand the comment into a NEEDSWORK to make it clear that the
direction is right, but the details need to be worked out
