The following patch does this.  Does this look like the thing to do?

The test case, with this patch, now looks like this:

 C-e                    ;; move-end-of-line
 C-x C-e                ;; eval-last-sexp
 a                      ;; 
 C-h l                  ;; view-lossage

I've looked at other in-tree usages of `recent-keys', and it doesn't
look like this should affect anything else.
