Hi Bruno,

    %reldir% without a following slash expands to a dot, and
    %canon_reldir% without a following underscore expands to an underscore.

    Suggested new text:

       A special feature is that if the fragment is in the same directory
       as the base Makefile.am (i.e., %reldir% is .), then
         - %reldir% together with a following slash will expand to empty,
         - %canon_reldir% together with a following underscore will expand
           to empty as well.

Thanks much. I added the dot/underscore information you wrote as well.
I pushed it, hope it looks ok ... -k
