The main problem is the MSYS2 build of xargs, so MSYS2 folks should
report this.

Yes, thanks.

It shouldn't be usd by default, because the only Findutils on Widnows
are GNU Findutils, so we should use -exec.  But grep-find-use-xargs is
a defcustom, so users could customize it to use xargs, and in that
case, we need -s 10000 as well.
