patch for ispell issues using header line

["Robert D. Crawford" <rdc1x@xxxxxxxxxxx>]

I have really been enjoying the header line that has recently shown
itself at the top of my buffers.  Reading this out as I switch buffers
has been much better than the old mode-line reading.  I have found one
issue that seems to be related.

If using the header line and running ispell-word, I get this error:

ispell-overlay-window: Window height 2 too small (after splitting) 

If I toggle the header line it solves the problem.

This patch turns the header line off if it is on and restores it after
ispell runs.
