Open stdin using its file descriptor so that a `dd skip=N` command in
a subshell does not consume all bytes from stdin.
For example, before this commit, multiple instances of `dd` reading
from stdin and appearing in a single command line would incorrectly
result in an empty stdin for each instance of `dd` after the first:
$ printf "abcdef\n" | (dd bs=1 skip=3 count=0 && dd) 2> /dev/null
# incorrectly results in no output
After this commit, the `dd skip=3` process reads three bytes from the
file descriptor referring to stdin without draining the remaining
three bytes when it terminates:
$ printf "abcdef\n" | (dd bs=1 skip=3 count=0 && dd) 2> /dev/null
