-/**
- * Implements the offside-rule for Twirlite fragments.
- *
- * This stage walks over the whitespace before each line of the Twirlite,
- * augmenting it with the corresponding open-{ and close-} such that an
- * un-modified Twirl parser can then parse it.
- *
- * The rule is simple: any line which starts with an expression potentially
- * opens a new block. Any text after the end of the expression is inside the
- * block, as well as any text on subsequent lines which are indented more
- * deeply.
