core.whitespace: split trailing-space into blank-at-{eol,eof}
People who configured trailing-space depended on it to catch both extra white space at the end of line, and extra blank lines at the end of file. Earlier attempt to introduce only blank-at-eof gave them an escape hatch to keep the old behaviour, but it is a regression until they explicitly specify the new error class. This introduces a blank-at-eol that only catches extra white space at the end of line, and makes the traditional trailing-space a convenient synonym to catch both blank-at-eol and blank-at-eof. This way, people who used trailing-space continue to catch both classes of errors. Signed-off-by: Junio C Hamano <gitster@pobox.com>
