Details:

Suppose I have a simple class "@me" with the following simple
"@me/display.m":


function display(x)
  disp(['input name is ' inputname(1)])
endfunction


With hg tip, I no longer get the empty string when I should, but rather some
cached version:


>> me(2)       % correct
input name is
>> y = me(3)   % correct
input name is y
>> me(4)       % wtf!, should be blank
input name is y
>> x = me(5)   % correct
input name is x
>> me(6)       % should be blank
input name is x
>> me(7)       % should be blank
input name is x


If I make some random change to the file "@me/display.m" then it works again,
until I display one that is assigned to a variable name.  This is why it looks
like some caching problem to me.

I haven't yet bisected, but something in the last 6 months or so as I had
previous "4.3.0+" versions working properly.
