[PATCH] emacs: remove thread archiving from show-advance function

[Jameson Rollins <jrollins@finestructure.net>]

I believe it's important to have a function to scroll through open
messages in the currently viewed thread, and ' ' is the most logical
keybinding for that.  However, the current function is far too
agressive in automatically archiving the thread and moving to the next thread
when getting to the end of the current thread.  This patch changes this
function to just stop when it gets to the end of the thread, thereby
giving the user a chance to act on the thread how they wish.
