intvec of size 1 is not compatible with int

[Oleksandr]

Dear Team,

Lars Kastner from Berlin has found the following glitch in Singular interpreter:

intvec v =1;
intmat m[1][3]=1,2,3;
m[1..1,1]=v;

produces:

   ? `int` = `intvec` is not supported
   ? expected `int` = `int`
   ? error occurred in or before STDIN line 3: `m[1..1,1]=v;`

Should Singular users work around this problem themselves or should we allow these conversions?

I propose the later which would be compatible with the following:

ring r;
vector V = -1;
matrix M[1][3]=1,2,3;
M[1..1,1] = V;

which works like charm!

fixed (missing case implemented).
