Public bug reported:
Using bash redirection with sponge does not work as expected. For
example, this will make test_file empty:
sed 's/^/prefix/' test_file | sponge > test_file
Instead, one should do this instead:
sed 's/^/prefix/' test_file | sponge test_file
I feel the man page should be updated to include this warning.
