revert some new features so that tex2lyx outputs format 247 proper again.

Browse Source 
The reverted features could (and should) be reapplied as soon as tex2lyx can output unicode (bug 4379).

The patch of this change can be found here:
http://bugzilla.lyx.org/show_bug.cgi?id=4379

and can be applied with -R in this case.
