Hi,

I wanted to use `checkdoc-current-buffer' programmatically.
Unfortunately, it seems the function `checkdoc-current-buffer' may check
part of a buffer that is not the current buffer.

Running the attached file 'test-checkdoc-buffer.el' with the command:


   emacs -Q  --batch --eval='(progn (find-file "./test-checkdoc-buffer.el") (eval-buffer))'


will print:


   ERROR `checkdoc-current-buffer' didn't check the current buffer


which means `checkdoc-current-buffer' checked (part of) the buffer:

   "*NOT THE BUFFER TO CHECK*"

instead of the requested buffer:

   "test-checkdoc-buffer.el"

Also, loading this file 'test-checkdoc-buffer.el' and using
`eval-buffer' will show the resulting wrong "*Style Warnings*" buffer.


It seems to me that, in `checkdoc-show-diagnostics', the instructions

    (pop-to-buffer b)
     ...
    (other-window -1)

are putting emacs in a window/buffer configuration that checkdoc does
not understand.



Bruno.
