git-rebase.txt: update note about directory rename detection and am

In commit 6aba117d5cf7 ("am: avoid directory rename detection when
calling recursive merge machinery", 2018-08-29), the git-rebase manpage
probably should have also been updated to note the stronger
incompatibility between git-am and directory rename detection.  Update
it now.

 Directory rename detection
 ~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-The merge and interactive backends work fine with
-directory rename detection.  The am backend sometimes does not.
+Directory rename heuristics are enabled in the merge and interactive
+backends.  Due to the lack of accurate tree information, directory
+rename detection is disabled in the am backend.
