[bitbake-devel] [PATCH] BBHandler/ast: Merge handMethod and handleMethodFlags

[Richard Purdie]

The functionality overlap between these two functions is significant and
its clearer to handle both things together since they are intimately
linked. There should be no behaviour change, just clearer code.
