Eric Paris 6de96b849c Default usage output to stdout 
If the command has not set an output explicitly everything will go to
stderr.  This makes a lot of sense, but is a huge PITA for people who
want to be able to grep the help output.  It is very common for users to
want to do

command --help | grep flag

This patch fixes that by default help output (but not error output like
an invalid command) to stdout instead of defaulting to stderr.

Eric Paris bf480fe628 New "example" section of commands 
We have a long and short description.  This adds an "Example" section.
Which can used to create better docs than putting it all in Long.
