Info node "(autotype)Executables" says that "Various interpreter modes
such as Shell script mode or AWK mode will automatically insert or
update the buffer's magic number..."

executable-insert is set to t but this doesn't happen.

C-x b foo RET
M-x sh-mode RET

No magic number is inserted, and you have to do it manually with
`C-c :'

Similarly, AWK mode doesn't automatically set it, either.

sh-set-shell does in some cases alter the first line.
So that statement isn't false.
