Tool should not eagerly read input stream in all cases

[HeavyWombat]

When retry is used in a setup where an outside routine relies on input stream processing, retry should not consume the standard input stream, because this breaks the whole flow:

#!/bin/bash

while IFS= read -r ENTRY; do
  echo "$ENTRY"
  retry true
done <<<"$(echo -e "one\ntwo\nthree")"
