If the file is found through searching (! tmp.empty ()), add in another
test that the directory is not the same as OCTAVE_DATA_DIR.

To me, the situation is no different if the file is found in OCTAVE_DATA_DIR or somewhere else.  If I happen to have my own file penny.mat but am confused about what directory I'm in, I'd like that to be an error rather than silently loading Octave's penny.mat file.

It's fine with me if we disable the warning by default, but I'd like to keep it.

I think it's possible to find out the location of the file that was loaded:  file_in_loadpath(fname) should find the same file as sys::env::make_absolute (lp.find_file (fname)), right?

In that case, I would disable the warning for myself---but I couldn't figure out how; I thought it'd be


but no:

octave:11> load x
warning: load: '/tmp/x' found by searching load path
