Matthew Flatt 2a67912028 scribble: discard partial output on exception ... This change avoids the problem of a bad "index.html" on a doucment rendering error, where the presense of an "index.html" would count as successes on a retry. original commit: e4e8a69e06863b423f4b7b716b369b002c2deea1		2014-05-09 09:37:24 -06:00
