Subject: Fix previous commit 1d327fd1dcd34023a3d5bb2c0ee7524593d44015.
X-Git-Tag: v8.2.0-rc1~6^2

Fix previous commit 1d327fd1dcd34023a3d5bb2c0ee7524593d44015.

Commit 1d327fd1dcd34023a3d5bb2c0ee7524593d44015 moved a function from the .cc
file into the .h file and made it inline. Subtly, it also snuck in a small
change in the code: it changed
  if (!something)
   {
     ...
   }

  if (something)
into
  if (!something)
    {
      ...
    }
  else

The problem is that the first code block in rare circumstances changed the
value of the variable something. It is remarkable that this only triggered
in a single test in the testsuite -- an indication that the testsuite is
after all reasonably good at finding even obscure problems, but also an
indication that the anisotropic refinement stuff is not particularly well
tested.
