I can see two approaches.  First, this warning has an ID,
Octave:data-file-in-path, and we could change the default on Octave startup
to disable this warning.  At that point, a user would have to actively turn
on this warning to see it.

Alternatively, I'm not sure why it is useful to know that the data file was
found in the load path.  We could just remove the code entirely.

Any votes one way or the other?

On the face of it, the warning is silly ("2+2 :  warning: addition: result 4 found by applying the rules of arithmetic"). I think the intent might have been to show the actual location of the file: I could see how it might be useful to capture that, if 'load' allowed 2 return parameters :


where x is the dataset being read and f is the filename.

All output should be catchable : it's neat that you can do


for i=1:length(s)   printf("%s: %s\n",s{i}.name,s{i}.description)   end

I thought there were instances where this was not the case (I seem to remember that pkg didn't always provide a way to capture the output), but I can't recall where I ran into it.

BTW, is there a way to cut through a cell array without a loop, like s{1:length(s)}.name?
