#2310: r.in.xyz: zcol should not be compulsory when method=n

-------------------------+--------------------------------------------------
In r.in.xyz, zcol is not necessary when method=n since all r.in.xyz does
is count the points. However, by default the module defines z=3, which
means that max_col becomes 3 and thus, for a simple file with only x and y
coordinates, max_col > ntokens (line 679 of main.c) and the modules fails
with
{{{
ERROR: Not enough data columns.
}}}
As it seems impossible to unset z, the only solution is to add a third,
bogus, column to the input data.
The code seems pretty much designed with the idea that a zcol is present
and it does not seem super-trivial enough for me do just change that.
I consider this a bug as it does seem counter-intuitive to require a zcol
when a method such as n is available.
