width of pretty_print() text output

edit

Consider a code example:

sage: L = [Matrix(ZZ,4,4)]*10
sage: pretty_print(L)
[
[0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]
[0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]
[0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]
[0 0 0 0], [0 0 0 0], [0 0 0 0], [0 0 0 0], [0 0 0 0], [0 0 0 0],

[0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]
[0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]
[0 0 0 0]  [0 0 0 0]  [0 0 0 0]  [0 0 0 0]
[0 0 0 0], [0 0 0 0], [0 0 0 0], [0 0 0 0]
]

It wraps up this list of matrices after 6 in a row, not matter how wide is my terminal window. How I can change this - e.g. specify the window width at which wrap the lines, or turn off wrapping at all?
