Adjust variable block applicability in dependency chains
Before the block used to apply to the set of prerequisites before the last `:`. This turned out to be counterintuitive and not very useful since prerequisite-specific variables are a lot less common than target specific. And it doesn't fit with ad hoc recipes. The new rule is if the chain ends with `:`, then the block applies to the last set of prerequisites. Otherwise, it applies to the last set of targets. For example: ./: exe{test}: cxx{main} { test = true # Applies to the exe{test} target. } ./: exe{test}: libue{test}: { bin.whole = false # Applies to the libue{test} prerequisite. } This is actually consistent with both non-chain and non-block cases. Consider: exe{test}: cxx{main} { test = true } exe{test}: libue{test}: { bin.whole = false } exe{test}: libue{test}: bin.whole = false The only exception we now have in this overall approach of "if the dependency declaration ends with a colon, then what follows is for a prerequisite" is for the first semicolon: exe{test}: { test = true } exe{test}: test = true But that's probably intuitive enough since there cannot be a prerequisite without a target.
