Then why isn't bidi-paragraph-direction the solution?  It can be put
in file-local variables.

I'm not sure I understand.  If you are saying that the manual could
use some improvement, please suggest what else should be told there.
If you mean something else, please tell what is it.

Sorry, I don't understand the recipe.  Without the LRM, that paragraph
should have been displayed flushed to the right margin, like this:

                                                             bla bla A

Is that your original display?  If so, where's the cursor when you
insert the LRM: to the left of A or to the right?

I cannot reproduce this, but what am I missing?
