50 processes the named files or the standard input writing
51 the standard output with tabs changed into blanks.
52 Backspace characters are preserved into the output and decrement
53 the column count for tab calculations.
55 is useful for pre-processing character files
56 (before sorting, looking at specific columns, etc.) that
61 argument is given, then tabs are set
63 spaces apart instead of the default 8.
64 If multiple tabstops are given then the tabs are set at those
68 puts tabs back into the data from the standard input or the named
69 files and writes the result on the standard output.
76 By default, only leading blanks and tabs
77 are reconverted to maximal strings of tabs.
80 option is given, then tabs are inserted whenever they would compress the
81 resultant file by replacing two or more characters.
