I haven't checked in a long time, but the last time I asked about this I 
was told that you can't edit a stack file in a text editor, because then 
the checksum won't match.

Is there a second file on the server that starts with a tilde(~)? That 
would be the original backup copy that Rev makes before saving. In that 
case, all you have to do is remove the tilde from the file name and the 
old copy will be restored. You'll lose all the changes since the last 
save, but at least your student will have the original back.
