I found that line 176 of std.format.d is wrong:
$(TR $(TD $(B '#')) $(TD numeric ($(B '0'))) $(TD Use leading
and thought it should be:
$(TR $(TD $(B '0')) $(TD numeric ($(B '0'))) $(TD Use leading
but Mr. Kenji Hara pointed that actually I could remove unnecessary text and made it:
$(TR $(TD $(B '0')) $(TD numeric) $(TD Use leading
