in the first case, vi is inheriting the standard input from his parent
process, xargs. the standard input of xargs is the pipe coming from
find, which is not a terminal...
in the second case, vi is inheriting the standard input from his parent
process, the shell, which is actually connected to a terminal, and
everything works fine.
