FYI: strftime.c fix obscure %s formatting bug

[Jim Meyering]

FYI, I've just checked in this change:

2005-08-17  Jim Meyering  <address@hidden>

        Make the %s format (seconds since the epoch) work for a negative
        number and when used with a zero-padded field width, e.g. %015s.

        * strftime.c (my_strftime): Move the `do_number_sign_and_padding'
        label so that it precedes the code to set `digits'.  Otherwise,
        %0Ns wouldn't work.  Before this change, `date -d @-22 +%05s' would
        print `00-22'.  Now, it prints `-0022', as it should.
