Thanks a lot, if the backslash in front of the [ can solve this
problem, then this is even an adequate fix for an existing
collection of keyboard macros.

I loaded the file that contains my keyboard macros and I created it
again with the patched version of insert-kbd-macro. The only
difference between the old and new file was the \ in front of the [.
So on that level I can say that your patch has fixed my problem with
apparently no undesired side effects.

Thanks a lot,

Roland
