Follow-up Comment #3, bug #34893 (project octave):

Actually, conv2.cc is in the DLD-FUNCTIONS and
it does provide 'valid'.  conv.m is in scripts/polynomical
and does not handle 'valid'.

The current distribution gives:
octave:1> conv([1:5].',[1:2].','valid') 
error: conv: SHAPE argument must be "full" or "same"
error: called from:
error:   /d/src/octave/hg/octave/scripts/polynomial/conv.m at line 55, column

but it also gives:
octave:1> conv2([1:5;1:5],[1:2],'valid') 
ans =

    5    8   11   14
    5    8   11   14


But, it would be good to start from the above results, 
not 3.4.2 or 3 which
were used in reporting this problem.
