Font.cpp: fix bug #8424

We must group the content which should be changed in size wit a pair of braces because the LaTeX size commands are otherwise switches. We already do so for many case, but not for the case that a size command is inside another command. This patch adds now always a brace pair around the selected text which is the safest method.
