gnucompability(xargs): when a filename contain an ascii space, it leads to an error #771
Description
Hi, findutils mainteners
that looks to me a capability issue, i see
relunsec@relunsec:~/software/findutils/target/debug$ echo -n " " > a.txt
relunsec@relunsec:~/software/findutils/target/debug$ sudo ./xargs -a a.txt ls
ls: cannot access '': No such file or directory
relunsec@relunsec:~/software/findutils/target/debug$ sudo /bin/xargs -a a.txt ls
a.txt build deps examples find find.d incremental libfindutils.d libfindutils.rlib locate locate.d testing-commandline testing-commandline.d updatedb updatedb.d xargs xargs.d
relunsec@relunsec:~/software/findutils/target/debug$ sudo ./xargs -a a.txt echo
relunsec@relunsec:~/software/findutils/target/debug$ sudo /bin/xargs -a a.txt echo
relunsec@relunsec:~/software/findutils/target/debug$ sudo ./xargs -a a.txt echo | xxd
00000000: 0a .
relunsec@relunsec:~/software/findutils/target/debug$ sudo /bin/xargs -a a.txt echo | xxd
00000000: 0a .
relunsec@relunsec:~/software/findutils/target/debug$ when doing an echo normal, but when ls no, while the gnu one xargs correctly interept that
