[H-GEN] emacs feature of the day: selective undo

[Martin Pool]

Select a region, then press C-u C-_ (in other words, undo with a
prefix argument.)  This is selective undo: it undoes the last change
in the region you marked, even if you've later made changes elsewhere
in the file.  You can repeat this command to undo more changes, or
move the cursor and then undo again to undo your undo.  Very cool.

EDLIN comes free with MS-DOS, and is expensive at the price.
