I guess you've already thought about this, but one solution is to just 
return the dot as part of the extension.  Then you get extension("foo.") 
== ".".  I noticed that .NET's getExtension method does this.

setExtension and defaultExtension would probably have to change to at 
least accept extensions that include the dot, if extension() is changed.
