Details:

when giving a column vector to legendre(), it will raise a "nonconformant"
error and quit, like this:

octave:6> dat=legendre(1,cos((0:10)'))
error: product: nonconformant arguments (op1 is 11x1, op2 is 1x11)
error: called from:
error:   octave/scripts/specfun/legendre.m at line 156, column 10

Matlab legendre() can handle vertical vectors, which yields identical
solutions to a row vector.

The following simple patch enables octave to do the same.
