mailling list archive suggestions

When I go to the mailing list archive single-email, the drop-down that lets
me choose other emails in the thread has a couple short-comings.

One is that the icon which indicates that the email has an attachment is
using the "empty-page" icon which generally indicates creation of something
new, not the "paperclip" icon which indicates an attachment.

Second, the presence of that icon messes up the level of indentation used
to indicate which emails are responses to which other emails. Perhaps an
all-white icon should be included in the front of all unadorned messages,
to keep the indentation correct.
