Now I can see what you mean, you are right. 'man' does not use the 's'
preproc according to man(1). So it should be removed.

Moreover 'man' seems to be sensitive about a blank preceding the preproc
string and because of the Emacs comment in the first line. Emacs is smart
to recognize the file's identifying string in the second line as well. So
the first line should be adjusted as follows.

-'\" st                        -*- nroff -*-
+.\"                        -*- nroff -*-                                       

The same applies to the other man page files man/*.n in the groff source.
