Hi

the %!warning block for testing functions checks the actual last warning
instead of the warnings received by the function.

For example, given the following function:


function test_warning
endfunction
%!warning <something> test_warning


testing this function should fail. However, if the previous warning was
actually "something", testing this function will pass even though the function
didn't actual emit any warning.

I don't know if I'm clear enough so here's an example to replicate the bug.
Provided that the previous function is defined somewhere:


> test test_warning  # this is as expected although for the wrong reason
  ***** warning <something> test_warning
!!!!! expected <something> but got X11 DISPLAY environment variable not set
> warning ("something")
warning: something
> test test_warning  # the function doesn't actually emit the warning, this is
incorrect
PASSES 1 out of 1 tests
