Comment backshade width consistency - Frontpage and Profile

[Ezd]

The backshade behind comments is very wide in the profile and narrow on the frontpage. This might or might not be a "bug" but the backshade should probably be the same width since both pages uses the same column width. The small change would make these 2 pages more consistent. Personally I prefer the narrow backshade width which just looks an inch "lighter".

this is caused by

body.internal-page div.activity-comments {width:auto;}

overriding

div.activity-comments {width:75%;}

in default.css

I'm making both full width, since this is better for threading.
