[Scilab-users] Accidentally displaying huge matrices

[Tim Wescott]

With the caveat that the threshold size that determines what gets
displayed in its entirety and what doesn't is tunable, this works for
me.

The root problem that I'm addressing is the pitfall of doing something
that prints for ever and ever just because I forgot the ';'.
