It's unclear what the '!' should negate in case of 'test_path_is_file
! file'.  What if 'file' does exists, but it's not a file but a
directory, socket, fifo, or symlink?  'test ! -f file' returns success
in these cases as well.

OTOH, it's quite clear what the negation should mean in case of
'test_i18ngrep'.
