<clixon-config xmlns="http://clicon.org/config">
  <CLICON_CLI_TAB_MODE>4</CLICON_CLI_TAB_MODE>
</clixon-config>

The TAB flags are not tested by regressions, only 0.
If they are available they should be tested. But since they are not they seem to have stopped working, at least flag 4.
So either they should be tested or they should be removed.
Do you think TAB = 4 is useful? do you need it in the application?

/* Steps to complete
 * 0: complete single step. 1: complete all steps at once
 */
#define CLIGEN_TABMODE_STEPS    0x04
