[Rd] read.table with fill = TRUE

[Gabor Grothendieck]

There seems to be a problem with read.table
when fill = TRUE in this case.  In the example
below, note that:
- there should be 4 columns, not 3
- some rows like row 6 are cut off at the end
- others like row 7 seem completely wrong

> Lines <- "x 1 b
+ x 1 a
+ x 2 b
+ x 2 a
+ x 2
+ y 1 a 1
+ y 10 a 2
+ y 10 a 10
+ y 10 a 1
+ y 2
+ var 10 a 2
+ var 2
+ y 10"
