patch 9.1.1537: helptoc: still some issues when markdown code blocks

Browse Source 
Problem:  helptoc: still some issues when parsing markdown code blocks
          (VimWei)
Solution: assign nextline to curline before starting the next loop
          iteration; when processing fenced code blocks, flip the
          skip_fence variable, update the test to be more comprehensive
