124616 - -moz-outliner-image does not work for attributes values containing a period.

Using the rdf:file datasource I am trying to assign an image based on file 
extension (which contains a leading period). 
outlinerchildren:-moz-outliner-image(FileNameCol, ext-.js ) etc.
This does not work. Adding a selection handler and displaying the FileNameCol 
properties shows that a property ext-.js is present. The presence of the period 
seems to prevent a match. 
As a test I wrapped the data source to produce an extension attribute without 
the period. The file icons then appear.
Sources supplied on request.

I doubt that a property containing a '.' can ever be made to work, since this
is used as a CSS pseudoelement name (if I'm not reading the code wrong); I 
don't believe that a pseudoelement may not contain the character '.' (just like 
element names and classes cannot).

So, unless there is some fancy footwork to, e.g., encode that character when 
dealing with in the outlinerbodyframe, this isn't going to work. Isn't it 
simpler to just use 'ext-js'/'ext-cpp' and trim the '.' before creating the 
property name?

I feared this would be the case. I need to wrap the datasource for other 
reasons, so this works for me.

Well, I'm not 100% certain of my diagnosis, but I'm fairly certain. If someone 
wants to point out that I'm wrong, then please do. 

But, if you're OK with this for other reasons, then that's good.
