commit 5c3f673c1ff25c835da6b905a63b36087aaa405e
Author: Mark Wielaard <mark at klomp.org>

Robustify WW8FormulaControl::FormulaRead reading SvStream.
The >>operator of SvStream doesn't initialize a variable if the stream
is faulty. So initialize the variables before usage to prevent reading
wrong/random bits.
