[PATCH v8 33/41] write_or_die: use warning() instead of fprintf(stderr, ...)

[Christian Couder]

In write_or_whine_pipe() and write_or_whine() when write_in_full()
returns an error, let's print the errno related error message using
warning() instead of fprintf(stderr, ...).

This makes it possible to change the way it is handled by changing
the current warn routine in usage.c.
