pathnames with spaces == bad

[Steve Vinoski]

I noticed that in the java subdirectory today, somebody committed a  
new directory named "Release Docs" under the doc directory. Let's  
please change that to "release-docs" or something like that, as  
pathnames containing spaces are just generally very hard to deal with  
in automated tools and such. I'm happy enough to commit the rename  
myself, but I just wanted to check before doing so to make sure  
someone isn't counting on the space being there for some reason.

thanks,
