PR11195: Prevent all nested argument substitution
Our existing protection only made sure that the first token in a
substitution wasn't a nested substitution. That's not sufficient when
there could be multiple tokens involved. This patch makes sure that no
nested tokens are ever allowed to be argument substitutions.
This also adds a cursor_suspended_line/column and resets the main
cursor_line/column to the beginning of the substitution, so errors will
point a little closer to the right place.
