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

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