+*** partial update of org-mode buffer
|
|
|
+ The sleekest solution to this may be using a comint buffer, and

|

|
|
|
+ the results as they are returned, including insertion into the
|
|
|
+ org-mode buffer. This may actually cause more problems than it is
|
|
|
+ worth, what with the complexities of identifying the types of
