OK, I'll commit that for gettext 0.18.2.

Ah, I didn't know that 'find' already has 'xargs' quasi built-in. Thanks
for teaching me!

I was going to say: Given that 'find' is only used when it's GNU find, I think
there is no need to add an extra check for whether argument accumulation via
'+' is supported.

But now I see that GNU find had a number of bugs in this area up until
recently. So I will hold off from using this feature for now.
