`pgrep`: output format

ordinary grep produces many different kinds of output

With one input file:

        matching line
        another matching line

With multiple input files:

        filename1: matching line
        another file: another matching line

With -l:

        filename1
        another file

With -q (or was it -s?):

The printing logic would have been quite complicated

Except I used a trick:

              printf $format, $file, $_, $.;

What is in $format?
