xargs is meant to only recognise blanks, that is <SPC>, <NL> and <TAB> as
separators in the arguments it receives on input.

GNU xargs happens to also treat all the other space characters (vertical tab
(\v), carriage return (\r), form feed (\f)) as separators which is wrong.

~$ printf '\f\r\va' | xargs printf %s | od -tc
0000000   a

Should output instead:

~$ printf '\f\r\va' | od -tc
0000000  \f  \r  \v   a
