Hi Davis,
There are two levels to what I'm envisioning.
First is the simple case when the killed buffer corresponds to a file with no
unsaved changes. In that case, undo-kill-buffer would have the same effect
as doing a find-file on that file again. Mainly the advantage is
convenience; M-x undo-kill-buffer will be approximately as fast as navigating
the filesystem to locate the file. Much more importantly, I do not have to
think; I can re-get that file (buffer) without interrupting concentration.
This becomes more important when working with many files in several
directories at once.
Second is when killing a buffer that has not been associated with a file, or a
buffer that has unsaved changes. This would have to be handled differently
from the above. The buffer contents would have to be cached somehow. I'd
probably have this be (de)activateable via a variable setting; if
deactivated, undo-kill-buffer would get the last saved version, xor fail.
Thanks,
Aaron
