bower automatically update bower.json

I run the following commands using bower 1.0.0: ``` mkdir testdir;cd testdir bower init #accept defaults bower install jquery -s #the -s is supposed to cause update of bower.json less bower.json ``` In bower.json I expect to see dependencies listed, but there are none. What is going on? NOTE: `bower install jquery --save` does work NOTE: The option I am referring to was documented through `bower help install` ``` **-S**, --save Save installed packages into the project's bower.json dependencies ```
