makepkg --noprepare option

[kachelaqa <kachelaqa@xxxxxxxxx>]

For version 4.1.1 of pacman, a --noprepare option was added to makepkg 
[1]. But, for version 4.1.2, the option is no longer available.

I've tried searching for some discussion of why the option was removed, 
but have drawn a complete blank so far. Can anyone shed any light on this?
