Well, it does make the error go away.
A problem is that `debugger-old-buffer' is not necessarily the same
buffer that was current when `eval-buffer' was called.
Example (with the patch):
Run emacs -Q
M-x toggle-debug-on-error RET
Insert this into *scratch*:
(get-buffer-create "foo")
(with-current-buffer "foo"
(error "foo"))
M-x eval-buffer RET
=>
Debugger entered--Lisp error: (error "foo")
signal(error ("foo"))
error("foo")
(save-current-buffer (set-buffer "foo") (error "foo"))
(with-current-buffer "foo" (error "foo"))
eval-buffer() ; Reading at buffer position 1
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is the position in the "foo" buffer.
`eval-region' has the same problem. In fact, regardless of that
problem the feature does not seem very useful at present when it comes
to eval-region.
E.g. if you do C-x h M-x eval-region RET and there is an error you
will get a note like this in the backtrace no matter where the error
occurred:
eval-region(1 500) ; Reading at buffer position 1
Since point doesn't move (eval-region apparently works differently
than eval-buffer in this respect) the value of point will always be at
the start or the end of the region (and these values are already
present in the backtrace).
