Indent version 2.2.12; One other question...

Also, one other question...

There is a passage that has me somewhat confused. It is in 
handletoken.c  now lines 1200 .. 1206.

It goes like this:

|    do||
||    {||
||        if (parse (lbrace) != total_success)||
||        {||
||            *file_exit_value = indent_error;||
||        }||
||    } while(0);|

The part that confuses me is the enclosing *do {* /<sequence>/ *} while(0);*

My understanding is that this simply means that the enclosed 
/|<sequence>|/   will be done, unconditionally, once only, in a manner 
that is exactly equivalent to simply ///|<sequence>|/ (or maybe |*{* 
/<sequence>/ *}*| if the enclosure gives some meaningful scope, which, 
in this instance, it does not) without the enclosing *|do {  } while(0);|*

Is there something subtle going on that somehow escapes me?

Please advise...
