Functions like make_array and indgen silently strip off trailing
shallow dimensions, but it is possible to override this using reform,
eg:

IDL> help, make_array(2,1,1)
<Expression> FLOAT = Array[2]
IDL> help, reform(make_array(2,1,1),2,1,1)
<Expression> FLOAT = Array[2, 1, 1]

The size function does accurately report the number of dimensions, I
think

IDL> print, size(make_array(2,1,1), /DIMENSIONS)
2
IDL> print, size(reform(make_array(2,1,1),2,1,1), /DIMENSIONS)
2 1 1

However, IDL is generally prone to chopping them off when you least
expect it, so is best to write code that will handle this.
