Yeah, we used to do this in the past, but now that we have added more type checking it's probably better to stop doing it like this. Using a very large number works, although it's not the nicest. Perhaps we could use -1, as a negative number is relative to the end? So -2 would be last-but-one line. Might be useful? It's at least existing, see :help list-index. -- Be nice to your kids... they'll be the ones choosing your nursing home. /// Bram Moolenaar -- [email protected] -- http://www.Moolenaar.net \\\ /// \\\ \\\ sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ /// \\\ help me help AIDS victims -- http://ICCF-Holland.org /// -- -- You received this message from the "vim_dev" maillist.
