[Bug-ddrescue] Small suggestion regarding the tutorial (in the online doc)

[Adder]

Dear author(s) of DDRescue,


Thank you warmly for all your work !

I would like to kindly suggest that a warning is added to the examples of usage 
in the manual:

    Section 7: A small tutorial with examples

The warning might state that it is important not to get mixed up the input 
file/partition/disk with the output file/partition/disk, at any of the number 
of times that ddrescue is run in an attempt to rescue the data. The results of 
that mixing up would be disastrous.

(I am thinking mainly of the "disk" alternative.)

Once ddrescue manages to copy the very first part of a disk, the disks will 
look to have the same number of partitions... thus, they may be difficult to 
distinguish.

Also, I would like to point out that it might be useful to offer a hint or two 
at how to distinguish the disks in such cases...

These are just very tiny and unimportant suggestions reflecting a narrow point 
of view... Thank you again for having created such a useful computer program !
