Makes it optional whether to indent arms in match expressions. Setting this to false may be desirable for people wishing to avoid double-indents, in that if the match arm is a block, the block will cause an extra indentation level, and if it isn't a block but just a single line, it's still easy to see the logic at a glance. This style is preferred in certain other languages with switch statements, e.g. Linux style C and the most common Java style.
