It's got this:

NROFF           /usr/bin/nroff -c -mandoc

/usr/bin/nroff has this inside:

   case $1 in
     -c)
       opts="$opts -P-c" ;;
     -h)
       opts="$opts -P-h" ;;

adding spaces between -P and {-c,-h} gives this error:

troff: fatal error: can't open ` -P -c -mandoc': No such file or directory

Adding -x to #!/bin/sh in /usr/bin/nroff suggests that for "man foo" the 
"foo" doesn't make it into the call to groff at the end of the script 
and that the additional args are being passed as a single argument:
