[PATCH] Fix snapshot link in tree view

[Petr Baudis <pasky@suse.cz>]

It would just give HEAD snapshot instead of one of the particular tree.

Perhaps we should also include snapshot in the global navbar? And perhaps
stgit should have a way to edit the mail before sending it so that I could
note this below the three dashes? ;-)
