pickaxe/style: consolidate declarations and assignments
Refactor contains() to do its assignments at the same time that it
does its declarations.
This code could have been refactored in ef90ab66e8e (pickaxe: use
textconv for -S counting, 2012-10-28) when a function call between the
declarations and assignments was removed.
