Comment (by mh35):

 If I pass only taxonomy and child_of parameter, this function returns
 direct and indirect children.
 {{{#!php
 <?php
 get_terms(array('taxonomy' => 'category', 'hide_empty' => false,
 'child_of' => 1));
 }}}
 This returns C1, C3, C4, C5, C2, C6 and C7. If I want to get only direct
 children, I pass parent parameter.
 {{{#!php
 <?php
 get_terms(array('taxonomy' => 'category', 'hide_empty' => false, 'parent'
 => 1));
 }}}
 This returns C1 and C2.
