OK, so the feedkeys() causes the safe state to be reset. That is correct, since Vim is then busy with processing input, which isn't considered safe. The problem is that with the "xt" argument to feedkeys() the input is processed right away, and we don't return to the main loop. I guess that we should check for a safe state at the start of feedkeys(), and if it's true and the input has been processed, check if it's still safe. -- Facepalm statement #7: "Last week I almost got pregnant!" /// Bram Moolenaar -- [email protected] -- http://www.Moolenaar.net \\\ /// sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ \\\ \\\ an exciting new programming language -- http://www.Zimbu.org /// \\\ help me help AIDS victims -- http://ICCF-Holland.org /// -- -- You received this message from the "vim_dev" maillist.
