[R] prefixing list names in print

[Laurent Deniau]

With

print(list(A="a",B="b"))

it displays

$A
[1] "a"

$B
[1] "b"

I would like to add a common prefix to all the list tags after the $. 
Pasting the prefix to the "names" does not work (appear after the $). 
For example if the prefix would be "P", it should display:

P$A
[1] "a"

P$B
[1] "b"

I tried to add a "name" attribute to the list or to add a prefix="P" to 
print but nothing works. Any hint?

Thanks,

	Laurent.
