We can all agree that seeing the full patch text when a patch is attached to a feature suggestion with your browser only is a good thing. But this can be improved even further.

Patch previews could show the full file text (instead of the patched portion only) on a nice formatted way like the one we see on the revision pages. That would make it easier to review patches.

By the way, the revision pages could also display the modified files as a whole with emphasized diffs.
