In your case, something like this should work (I assumed the four  
tabs needs to be at the begin of the line):

{   completionCommand = 'perl -pe "s/^\t{4}($TM_CURRENT_WORD.*)\$|.* 
\n?/\$1/" <"$TM_FILEPATH"';
     disableDefaultCompletion = 1;
}

Add that as a preferences item and set the scope for it to  
“splay.character”. One caveat: it extracts completions from the saved  
file (the completion command ought to get the entire document as  
stdin, but it currently doesn't).
