531    Makes sure that the first character of actual line content lies on a
532    tab stop, so that the alignment of tabs looks normal.
533    This is useful when combined with @samp{-H} (which is implicit when
534    there is more than one file to search), @samp{-n}, and @samp{-b};
535    these options prepend their output at the beginning of the displayed
536    line, before the actual content.
537    In order to improve the probability that all matched or context lines
538    from a single file will all start at the same column, this also causes
539    the line number and octet offset (if present) to be printed in a minimum
540    size field width.
