[bug #51151] [wishlist] xargs -o support for interactive commands

[Dale Worley]

Follow-up Comment #3, bug #51151 (project findutils):

I suggest this form as a workaround, particularly because it causes Emacs to
see as stdin whatever the stdin in effect in the environment.  I'm not sure
there's a way that we could package that into an option for xargs, though.

exec 3<&0
find ... | xargs sh -c 'emacs "$@" <&3'
exec 3<&-
