Based on the source[1] it currently trims:

* '; ' => ';'
* ': ' => ':'
* ' {' => '{'
* '{ ' => '{'
* ', ' => ','
* '} ' => '}'
* ';}' => '}'

That still leaves room for improvement of 3 cases (found out through bug 35492).

* Space before }
> > return CSSMin::minify("foo { prop: foo }");
> foo{prop:foo }

* Space before :
> > return CSSMin::minify("foo { prop : foo; }");
> foo{prop :foo}

* Space before ;
> > return CSSMin::minify("foo { prop: foo ; }");
> foo{prop:foo }

* Space before ,
> > return CSSMin::minify("foo { prop: foo , bar ; }");
> foo{prop:foo ,bar }

Especially the latter two (space before comma or semi-colon) are a fairly common programming style by the "space-extremists".

foo {
    prop:
      voo( .. ) ,
      voo( .. ) ;
    prop: foo ;
}

I'm not going to be bold on this one because I haven't checked whether there are any side-effects to these 4 changes, but they seem easy gains :)
