Macros containing callbacks with function calls inside are expanded within callback

[JackWilliams-FractureSounds]

For example, this compiles:

on init
  declare kccn
end on

function cc_notify   { invoke this from host's controller callback when using amode = 1 }
    kccn := CC_NUM   { latest CC that changed }
end function

on_cc_notify

macro on_cc_notify   { create controller callback and invoke cc_notify }
  on controller
    cc_notify
  end on
end macro

...But this doesn't:

on init
  declare kccn
end on

on_cc_notify

function cc_notify   { invoke this from host's controller callback when using amode = 1 }
    kccn := CC_NUM   { latest CC that changed }
end function

macro on_cc_notify   { create controller callback and invoke cc_notify }
  on controller
    cc_notify
  end on
end macro

The cc_notify function gets expanded within the on controller callback, which causes a syntax error

Compiled code:

on init
declare sksp_dummy
declare concat_it
declare concat_offset
declare string_it
declare list_it
declare preproc_i
  declare kccn
end on

  on controller
    cc_notify

function cc_notify   
    kccn := CC_NUM   
end function

  end on
