Summary:                    Add -o (reopen stdin) option to xargs(1)
Description: 
Now that 243 is accepted, I would like to request the addition of another
option to xargs(1) to make it really useful. It’s a BSD thing:

     -o      Reopen stdin as /dev/tty in the child process before
executing
             the command. This is useful if you want xargs to run an
interac-
             tive application.

I’ve been using this a *lot*, as something like…

$ git find \*.h -print0 | xargs -0o $EDITOR

… (where https://github.com/mirabilos/git-find/ is the tool in question),
or with just a simple find, or a (git) grep -Z. I also have been able to
successfully convince GNU coreutils to add precisely this (they also added
a GNU --long-option but added it with -o for BSD compatibility). (I know I
should use -0or but I lazily skip the -r if I know there’s at least one
anyway.)

Desired Action: 
In SYNOPSIS, change -0ptrx to -0optrx.

In DESCRIPTION, where it says the results are unspecified if the utility
reads from stdin, add unless the -o flag is given.

In OPTIONS, add:

.It Fl o
Reopen stdin as
.Pa /dev/tty
in the child process before executing the command.
This is useful if you want
.Nm
to run an interactive application.

In INPUT FILES, mention that -o also uses /dev/tty.

Possibly add a suitable example; do we have grep -Z yet in POSIX (it’s
not in 243)? Otherwise, 'find . -name \*.h -print0 | xargs -0or $EDITOR'
will probably do.
