Description of problem:
man prints some superfluous and incorrect diagnostics when invoked
with -a on some man pages.

The reason is that it locates certain man pages twice, once in section
1 (for example), then again in section 1p, despite the fact that the
man page does not exist in section 1p.

Some debugger work shows that the source of the problem is in
manfile.c, in the function manfile_from_section().  Here's the culprit:

if (res == NULL && isdigit(section[0]) && section[1]) {
     char sec[2];
 
     sec[0] = section[0];
     sec[1] = 0;
     for (mp = manpath; *mp; mp++) {
        append(&res, manfile_from_sec_and_dir(*mp, sec, name, flags));
          if (res && (flags & ONLY_ONE_PERSEC))
               break;
     }
}
                                                                     
                                                                     
          
Here, when section contains "1p", sec contains "1", and so
manfile_from_sec_and_dir() locates the man page in section 1, for the
second time (the first time was when section contained "1").

The result is that the 'struct manpage *res' in manfile() contains a
duplicate entry, which triggers an apparently silly duplication
complaint from is_different() in different.c.
