R devel - Nov 2000 - printing of lists (PR#746)

This looks to me like a bug in the print method for lists.  In printing 
"test.list" below, the labels $A$subset and $B$subset fail to appear.

I find the same behaviour under linux and Windows (using R 1.1.1 -- 
for version info see below) with R --vanilla.

Bug confirmed, with the current "R-devel"opment version.
Another slight variation on the theme:
> list(A=list(bla="Y~X",no2=TRUE), B=list(blu=Y~X,no2=TRUE))
$A
$A$bla
[1] "Y~X"

$A$no2
[1] TRUE


$B
$B$blu
Y ~ X


[1] TRUE
