Hello,

The attached patch adds the command `edmacro-set-macro-to-region-lines` 
for quickly reducing the presented keys to those in the region, and adds 
the user option `edmacro-reverse-key-order` for showing the most recent 
keys first.

These two changes are useful for `kmacro-edit-lossage`.  My use case is 
that I would like to quickly create a keyboard macro from some of my 
recent key presses, but Edmacro is slow to use when the lossage size is 
large.  When it is large, I must jump to the bottom of the buffer, then 
cut the desired lines, then jump back up, then delete the remaining 
lines, then paste the cut lines, then press `C-c C-c`. If I use 
`delete-selection-mode`, I can combine two of the steps.  With this new 
change from the patch, I can move down a few lines, select a few lines, 
then press `C-c C-r`, then press `C-c C-c`.

Thank you.
