5 * Tests for the options '-eei' and '-neei'.
6 *
7 * The option '-eei' enables extra indentation on continuation lines of the
8 * expression part of 'if' and 'while' statements. These continuation lines
9 * are indented one extra level.
10 *
11 * The option '-neei' indents these conditions in the same way as all other
12 * continued statements.

79 * following statement, which would be confusing.
