when using the shell, the --quiet parameter does suppress the output from the --eval command

For example:

$ mongo <server>/db script.js --eval 'yyyymm="2011-11"'
MongoDB shell version: 2.0.1
connecting to: <server>/test
2011-11

Now with the --quiet parameter, the banner is suppressed, but eval seems to be adding output to stdout.

$ mongo <server>/db script.js --eval 'yyyymm="2011-11"' --quiet
2011-11

It'd be an improvement if the results of the --eval commend respected the --quiet flag.
