[Rd] crash with scan(..., what=list(,,)) (PR#802)

[paradis@isem.univ-montp2.fr]

When reading a file with scan(), the following crashes R under Solaris and
WinNT 4.0 (versions below):

> ads <- scan("Bltiadu.dat", what=list(,,))

Would an error message be more logical? Note that the followings work (the
data file has 201 lines and 3 columns):

> ads <- scan("Bltiadu.dat", what=list(0,,))
Read 603 lines
> ads <- scan("Bltiadu.dat", what=list(0,0,0))
Read 201 lines
> ads <- scan("Bltiadu.dat", what=list(0,0,))
Read 302 lines
Warning message: 
line 1 did not have 2 elements
