eval-last-sexp -> syntax error -> deletes rest of buffer!

[David Reitter]

Place the following in the middle of a buffer (with text following):

`[(,test ,)]

Set the point right after the (malformed) expression and hit C-x C-e.
You will find that an error is correctly reported (invalid-read- 
syntax ")"), but that the complete rest of the buffer (after the  
point) IS DELETED.

Annoyingly, undo doesn't bring it back, nor is the deleted part of  
the buffer  properly killed and put into the killring.


This happens on today's CVS build. The bug has been around for a while.
