I don't know of one. This is Splus 3.x compatible behaviour, it seems,
but it's none too logical to have this happen even with sep="\n"...

$ cat > junkx
line 1
line 2     

line 4
$
...
[Splus]
> scan(file='junkx',what='',sep='\n')
[1] "line 1" "line 2" "line 4"
> read.table(file='junkx')
    V1 V2 
1 line  1
2 line  2
3 line  4

Perhaps we want to add an argument to control this?
