The upstream go-flags project do not support terminated options like ``find -exec``. The repo was forked and the feature was introduced in [0]. Until the PR [1] is merged in the upstream repo, we need to maintain and point to a fork with the features there. Refs: - [0] rebornplusplus/go-flags@1dbaf44 - [1] jessevdk/go-flags#395

The overall idea looks reasonable to me, but I have a few comments related to making it more general and cleaning it up a bit.

Nice work! Just a couple of minor nits comments (and I kinda disagree --term \; that should be disallowed).
Enable option to receive arguments until specified terminator
is reached or EOL has been found. This is inspired from
``find -exec [commands..] ;`` where commands.. is treated as
arguments to -exec.
If for an option ``opt``, ``terminator`` is specified to be
; (semi-colon), in the following
$ program [options] --opt v --w=x -- "y z" \; [more-options]
--opt will receive {"v", "--w=x", "--", "y z"} as its
argument. Note that, the -- inside will also be passed to
--opt regardless PassDoubleDash is set or not. However,
once the scope of --opt is finished, i.e. terminator ;
is reached, -- will act as before if PassDoubleDash is set.
Use tag ``terminator`` to specify the terminator for
the option related to that field.
Please note that, the specified terminator should be a
separate token, instead of being jotted with other characters.
For example,
--opt [arguments..] ; [options..]
will be correctly parsed with terminator: ";". However,
--opt [arguments..] arg; [options..]
will not be correctly parsed. The parser will pass "arg;",
and continue to look for the terminator in [options..].
