And  exactly  in the same way, using an end-of-input
trap:

     .de1 an-end
     .  nr % 1
     .  pl +4v
     .  fl
     .  sp 3
     .  an-p-footer
     .  pl \\n[nl]u \" <- trim page length
     ..
     [...]
     .if \n[cR] .em an-end \"<- Turn on single-page mode if cR > 0

So, this behavior can controlled via the  cR  number
register,  and  you can set number registers on com-
mand-line when invoking groff with the -r option.
