 Hi,
 
 there is no problem with mandoc.  The top(1) manual is just plain
 broken:  In the roff language, to interpolate the number contained
 in a register, you can use the \n escape sequence.  You cannot use
 the .af request for that purpose, that one serves a completely
 different purpose, see the roff documentation.  Groff renders it
 exactly the same way as mandoc.
 
 The following patch fixes the broken manual page.
 
 Yours,
   Ingo
