Subject: [PATCH] WIP Remove + From Mode in BaseWriter (#2657)

BaseWriter openFileHandle opens its output file with mode `wb+`. We don't appear to attempt any reads on the file after it is opened in write mode, so `wb` should be sufficient. This may have been a factor in the need for PR #2326, and is likely to be responsible for issue #2372.
