49 * Historically, [@*]<carriage-return> and [@*][@*] executed the most
50 * recently executed buffer in ex mode. In vi mode, only @@ repeated
51 * the last buffer. We change historic practice and make @* work from
52 * vi mode as well, it's simpler and more consistent.
54 * My intent is that *[buffer] will, in the future, pass the buffer to

77 * The buffer is executed in vi mode, while in vi mode, so simply
78 * push it onto the terminal queue and continue.
81 * Historic practice is that if the buffer was cut in line mode,
82 * <newlines> were appended to each line as it was pushed onto
83 * the stack. If the buffer was cut in character mode, <newlines>
84 * were appended to all lines but the last one.
87 * Historic practice is that execution of an @ buffer could be
88 * undone by a single 'u' command, i.e. the changes were grouped
89 * together. We don't get this right; I'm waiting for the new DB
90 * logging code to be available.
