Comment (by ballapete):

 This ansi-term in GNU Emacs is too dumb to be useful… it's just like a
 piece of hardware, allows via bash to scroll in command history, but I
 have no change to insert and execute the contents of macros – and possibly
 it's not possible to work on the contents of this `*ansi-term*` buffer.

 It's ok for those folks who have endless time to achieve something. I'm
 not going to use it.
