17/* By default, convert all tabs to spaces.-
18 Preserves backspace characters in the output; they decrement the-
19 column count for tab calculations.-
20 The default action is equivalent to -8.-
21-
22 Options:-
23 --tabs=tab1[,tab2[,...]]-
24 -t tab1[,tab2[,...]]-
25 -tab1[,tab2[,...]] If only one tab stop is given, set the tabs tab1-
26 columns apart instead of the default 8. Otherwise,-
27 set the tabs at columns tab1, tab2, etc. (numbered from-
28 0); replace any tabs beyond the tab stops given with-
29 single spaces.-
30 --initial-
31 -i Only convert initial tabs on each line to spaces.-
