Let the mandoc.db(5) test suite work with parallel make (make -j),

by making sure that different tests use different directory names
for their work such that they do not collide.
As a side benefit, this allows keeping the complete working directories
of the tests until "make cleandir" is run, which may occasionally
help debugging when something breaks.

The failure with make -j was detected and reported by anton@,
who also reviewed, tested, and OK'ed this somewhat lengthy patch.

 .Nd create files such that inode numbers hash in a defined order
 .Sh SYNOPSIS
 .Nm makeinodes
+.Op Fl r
+.Ar dirname
 .Sh DESCRIPTION
 The
 .Nm
 utility creates a directory
-.Pa man/man1/
+.Ar dirname
+with a subdirectory
+.Pa man1
 and two empty files
-.Pa man/man1/1
+.Pa man1/one.1
 and
-.Pa man/man1/2
-such that the lowest six bits of the inode number of file 1
-are smaller than the lowest six bits of the inode number of file 2.
+.Pa man1/two.1
+such that the lowest six bits of the inode number of file
+.Pa one.1
+are smaller than the lowest six bits of the inode number of file
+.Pa two.1 .
+If
+.Fl r
+is specified, the reverse order is produced.
 .Pp
 This is useful to test the behaviour of the
 .Xr makewhatis 8
 program which hashes files with
-.Xr ohash 3
+.Xr ohash_init 3
 according to their inode numbers, such that fully testing all the
 code paths requires test files hashing in a well-defined order.
 .Pp
 Once the files have been created with
 .Nm ,
 their content can be provided with
-.Xr cat 1
-and they can be renamed as desired with
-.Xr mv 1 .
+.Xr cat 1 .
 .Sh EXIT STATUS
 .Ex -std
 It may fail when creation of a directory or file,
