[Proj] cs2cs produces partial output when called from matlab

[Charles Karney]

This works OK for me (Matlab 2013a on Linux).  Perhaps make sure that
1.tmp really has only the 1 number in it and doesn't contains carriage
returns that cause later numbers to overwrite earlier ones.  Failing
that, switch to Octave!
