Problem (or possibly several interesting features) with formatting of  
author(s) signature lines under MT 5 (external letter) of the mm macros.

--------------------------
example:
single author, one argurment
        get lead dashes at left margin "--" in signature line
with:
.AU "John 1 Rupley"
.SG gives:
       --                            John 1 Rupley

--------------------------
example:
two authors, each with reference data (2 or more args)
         reference data at left margin has arg 2 replicated:  "jar2/jar2"
with:
.AU "John 1 Rupley" "jar1"
.AU "John 2 Rupley" "jar2" "Biosci." "Biochem. Mol. Biophys."
.SG gives
                                         John 1 Rupley

Biosci.-Biochem. Mol. Biophys.-jar2/jar2 John 2 Rupley

--------------------------

To demonstrate the above, run the attached file through troff -mm and  
grops.  The file is configured to show the result of the first  
example above.  For other examples, reset the ".ig" -- ".." pairs.


Problem is in the macro "let*mt-sign" of m.tmac.

One possible revision of this macro is given on line 73ff of the  
attached file.  Delete the ".ig" at line 74 to test it.

Thank you,

Best wishes,
