When you defocus the TeXmacs window, it will scroll to the current position
of the cursor. I find this behavior particularly frustrating, especially when
reading the TeXmacs documentation....

Here is a tentative patch to fix this problem. I'm not sure about what I am
doing there, but it works and do not seem to have undesired side effects.

Merry christmas.
