Samba does properly manage CR-LF by *not* translating it.  There are a 
lot of tools that can convert between Unix termination (<LF>), Mac 
termination (<CR>) and MS termination (<CR><LF>) but *all* require some 
form of user intervention to get it right.

It is not theory, it is practice.

No, the user does not have access to smb.conf.  The system manager would 
have to establish any such policy, though the policy could be user based.

A .doc file is most often an MS Word document, and converting line 
termination would probably ruin it.  Regarding the .txt file, the system 
manger would need to establish a policy for each user *and* each machine, 
requiring that the client machine type be determined at connection time.

The reason that this is not done is that there is no way to automatically 
determine both the OS of the machine reading the file and the termination 
in use in the source file.

Note, though, that the smbclient utility *can* translate termination. 
Once again, this is under USER CONTROL.  If you want to translate 
<CR><LF> to <LF> or the other way 'round, copy the file using smbclient.
