/*
 * Tests for the parser symbol psym_if_expr_stmt_else, which represents the
 * parser state after reading the keyword 'if', the controlling expression,
 * the statement of the 'then' branch and the keyword 'else'.
 *
 * If the next token is an 'if', the formatting depends on the option '-ei' or
 * '-nei'.  Any other lookahead token completes the 'if' statement.
