patch 9.2.0072: inside_block() uses wrong index in loop

patch 9.2.0072: inside_block() uses wrong index in loop

Problem: inside_block() always checks the flags of the top-most stack
entry instead of the current loop index.
Solution: Use the loop index 'i' to check all levels of the condition
stack (Weixie Cui).
