No, we don't. Perhaps it would work if it was at the end of the
commandline.

next_arg checks that quoting is closed.

It was possible but undocumented with previous behavior - you would
place the quote in the middle and the closing quote at start or end so
that next_arg would remove the closing quote but not the one in the
middle.

It would be also possible with shell-like backslash escaping but that
is not implemented.

Thanks
