Using “M-x insert-kbd-macro” can insert an incorrect kmacro form for a
named macro, while still correctly inserting the “last-kbd-macro”.

To see this, we’ll define a macro that simply inserts the HTML string
“<b>hello</b>” (press F3, type the previous string, then press F4).
We’ll name this macro “bold-hello” using “C-x C-k n”.

Inserting the definition to the last macro (using “M-x insert-kbd-macro”
and leaving the prompt blank) returns:

(setq last-kbd-macro
   (kmacro "< b > H e l l o < / b >"))

Inserting the definition to “bold-hello” (using “M-x insert-kbd-macro”
and typing “bold-hello” at the prompt) returns:

(defalias 'bold-hello
   (kmacro "<b> H e l l o < / b >"))

Notice the difference in “< b >” vs “<b>”.  The “bold-hello” command
doesn’t work, printing the message:

“After 0 kbd macro iterations: Keyboard macro terminated by a command ringing the bell”

I think this may have to do with the use of “key-parse” in “kmacro” (see
“(find-function 'kmacro)”).

(key-parse "<b>hello</b>") returns
“[b 104 101 108 108 111 60 47 98 62]”
but
(macro--string-to-vector "<b>hello</b>") returns
“[60 98 62 104 101 108 108 111 60 47 98 62]”

The latter form is used in “insert-kbd-macro” when inserting
“last-kbd-macro”.


You can also quickly replicate the issue by evaluating the following
form:

(progn
  (setq last-kbd-macro "<b>hello</b>")
  (kmacro-name-last-macro 'bold-hello)
  (let ((temp-buffer (generate-new-buffer "*macros*")))
    (with-current-buffer temp-buffer
      (insert-kbd-macro (intern ""))
      (insert-kbd-macro 'bold-hello))
    (display-buffer temp-buffer)))
