A term-mode buffer doesn't seem to duplicate with M-x clone-buffer very
well. For example
emacs -Q
M-x term
top Ret ;; run the "top" program
C-c M-x clone-buffer
=> gets multiple inserts of the top output
where I hoped the cloned buffer would have refreshing top output,
instead of appending and growing the buffer.
Nosing around the code it looks like clone-buffer runs up a new
subprocess well enough, but that presumably something in the `term-mode'
setups doesn't come out right.
A line-oriented program like the default /bin/bash that M-x term offers
seems a bit better, though point isn't left at the end of the new
prompt.
