1. Fix some print_msg to be print_err
2. Rename the function to make error messages go to stderr to
redirect_output_stderr, which is more sensible.
3. Make the -stdout switch always force error messages to stderr
4. Add the "-err" switch to all programs, which allows the user
to choose whether they prefer errors to go to stdout or stderr
That last is something I meant to do as part of the stdout/stderr
changes - thanks again to alexw for causing me to get round to it.
This now allows:
cat data/ed24p_11.ts | ts2ps -stdin -stdout | ps2ts -stdin -stdout | mplayer -
to work -- it didn't before.
