vim-patch:9.1.1389: completion: still some issue when 'isexpand' contains a space (#34026)

Problem:  Cannot get completion startcol when space is not the first
          trigger character (after v9.1.1383)
Solution: Detect the next comma followed by a space in the option string
          and use in next compare loop (glepnir)

closes: vim/vim#17311
