Here it is.
First of all, sorry for having generated a lot of noise. I completely 
misunderstood the meaning of --no-preserve=links. Having get rid of 
that, the differences in the results of the tests are a lot less.

$ fgrep "DIFFERENCE in Test: " testit.log | sed 's/^.*: //'
cp  -l   filelink ...
cp  -l  --preserve=links filelink ...
cp -L -l   filelink ...
cp -L -l  --preserve=links filelink ...
cp -L -l -R  filelink ...
cp -L -l -R --preserve=links filelink ...
cp -H -l   filelink ...
cp -H -l  --preserve=links filelink ...
cp -H -l -R  filelink ...
cp -H -l -R --preserve=links filelink ...

I think they are all legit (full log and differences summary attached).

* Changes with regard to the last patch posted by Bernhard.

=== Minor changes

- use 'dereference' instead of 'deref' in order to be consistent with 
   'x->dereference' and for passing the "grep test"[0]
- use 'command_line_arg' instead of 'cli_arg' in order to be consistent 
   with an already used variable and for passing the "grep test"
- move up the declaration of bool dereference in order to use it for 
   every invocation of create_hard_link()
- clean up the initialization of 'flags' in create_hard_link()

[0] i.e.: http://jamie-wong.com/2013/07/12/grep-test/

=== Major changes

- dereference by default (i.e.: unless --no-dereference is used) the 
   source files.
   I promise that I will not insist anymore :), but I really think this 
   is important for consistency from a user point of view.

Ciao,
Gian Piero.
