Well, we are trying over time... :)

It should all use 4 space for python functions. There is however a twist
which is due to the way we handle _prepend and _append. Those prepends
and appends have whitespace too and I seem to remember issues with
whitespace matching.

Yes, this is horrible. This is why that file hasn't been touched for
whitespace though.

I'd be interested to see how much breakage we get from changing it. In
fact I just tried it, the result:

http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=rpurdie/t14&id=3db917bfb2455715a3a3a542ea831d05ca1cf9f7

the particularly nasty bit:

python populate_packages () {
	# Whitespace is deliberately a tab here due to the number of packages which
	# prepend this fuction :(
	populate_packages_core(d)
}

other than that it does seem to be working as long as I tweaked the
busybox recipe and update-alternatives too. We could go through and
change all the populate_packages_prepend functions but its the ones
outside OE-Core I worry about. I also worry there are some _append
functions now silently failing though :(.

Cheers,

Richard
