 * Tests for the options '-eei' and '-neei'.

 * The option '-eei' enables extra indentation on continuation lines of the
 * expression part of 'if' and 'while' statements. These continuation lines
 * are indented one extra level.
 *
 * The option '-neei' indents these conditions in the same way as all other
 * continued statements.
