bug#37057: 25.2; Calc; Key erroneously recorded twice in keyboard macro

[Christoph Arenz <tiga.arenz@web.de>]

In Calc enter:
90 <RET> S <f3> I S <f4>
S <f4>
The first key sequence gives 90 again.
The second key sequence shows 1, however expected is 90 as well.

Looking at the recorded macro with C-x C-k e <RET> shows this:
Command: last-kbd-macro
Key: none

Macro:

ISS            ;; self-insert-command * 3



<view-lossage> shows this:
  C-x * [calc-dispatch]
  * * 9 [calcDigit-start]
  0 [calcDigit-key]
  <return> [calcDigit-nondigit]
  S [calc-sin]
  <f3> [kmacro-start-macro-or-insert-counter]
  I [calc-inverse]
  S [calc-fancy-prefix-other-key]
  S [calc-sin]
  <f4> [kmacro-end-or-call-macro]
  S [calc-sin]
  <f4> [kmacro-end-or-call-macro]

It looks like the one key press of 'S' was seen twice (as
[calc-fancy-prefix-other-key]
and as [calc-sin]) and also recorded twice in the keyboard macro.
Using the macro thereafter leads to a wrong result.
