.Nm causes a line break in SYNOPSIS

.Nm
.Nm

COMMAND LINE: './test-groff' '-mandoc' '-Tascii' 'test.n'

DESCRIPTION OF INCORRECT BEHAVIOUR:
The command '.Nm' causes a line break in SYNOPSIS.  This is probably desirable 
because manual pages such as "pftp.1" depend on it; however, this feature is 
not mentioned in "tmac/groff_mdoc.n".
Here is the result:

NAME
     name name

SYNOPSIS

     name
     name

SUGGESTED FIX:
Add a statement to that effect to groff_mdoc manual page.
