Bugs in new key placement code

[Ethan M. <merritt@u.washington.edu>]

Try the following:

  set key box title "Foo"
  splot 1,2,3,4,5

Everything is OK so far.  Now try:

  set key rmargin
  replot

That's not what I expected, but let's proceed.

  set key tmargin
  replot

Huh?  The box is no longer correct.

  set key lmargin
  replot

Seems to be a no-op. Key is still broken.

  set key title "A much longer title"
  replot

And now it's obvious that the title centering is not
correct, either.

Now let's start again (2D this time)

  reset
  set key box title "A much longer title"
  plot 1,2,3,4,5

In 2D the title is centered, but the box is not adjusted
to fit it.
