bug#28569: 25.2; dired-sort-toggle-or-edit vs. quote marks

[積丹尼 Dan Jacobson]

I think the user should just be able to enter things to C-u s just like
he does in the shell. And C-u s should parse the arguments for him.
I don't see what the advantage of having him enter
"--option=value with spaces"
instead of
--option="value with spaces" is.
Both should work in my opinion, and whatever dirty work of parsing
should be done behind the scenes by the program.
