move backwards

Hi,
my problem, demonstrated with file "1234567abc.txt":

I try to move "abc" backwards with "backwards" checked, "Move relative" unchecked in the "move"-procedure.

I use for instance
Move from: 1
Move count: 3
Move to: 4

to get "1234abc567.txt", as expected.

Or
Move from, Move count as above, but
Move to: 3
gives "12345abc67.txt", as expected.

But Move from, Move count as above, and Move to: 2, I expect "123456abc7.txt", but get
"1234567abc.txt" instead.

Its easy to get around this problem using different procedures. Nevertheless this looks like a bug, or do I misinterpret the "backwards" counting?
