[bug #61009] xargs need option to immediately stop on command fail

Follow-up Comment #2, bug #61009 (project findutils):

[comment #1 comment #1:]
> POSIX [1] specifies the following conditions when xargs shall terminate
processing:
> * child exits with 255,
> * child was killed by a signal, or
> * when reading the 'eofstr' string if the '-E eofstr' option is given, or
> * when regularly reaching EOF when reading from stdin.

POSIX standardize those features that are already implemented by somebody
;-).

> Still, our xargs might implement such an option as a GNU extension.

That's great!

> I would recommend a long-option like --stop-on-error for such an extension.

This would be great if we have short option in addition to long, because this
is a normal(usual) case when we want to early stop on error, i think.

> Why did you propose '-F'?  Is there any precedence in other xargs
implementations?

No. This is my invention just for demonstration :-). I think about it like -F
= --fail-on-error. But -S for --stop-on-error will be good too.

> Regarding the examples - and just to be sure:
> I assume that the reproducer with 'cp' was just a simplification to
demonstrate your actual use case, right?

Yes. You are right.
