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