[tor-commits] [tor/maint-0.4.0] Improve logging for 28614.

commit 5613968d57cb07cc5a66e97c58bd39c22b86a50a
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>

    Improve logging for 28614.
    
    When we fixed 28614, our answer was "if we failed to load the
    consensus on windows and it had a CRLF, retry it."  But we logged
    the failure at "warn", and we only logged the retry at "info".
    
    Now we log the retry at "notice", with more useful information.
    
    Fixes bug 30004.

+  o Minor bugfixes (logging):
+    - On Windows, when errors cause us to reload a consensus from disk, tell
+      the user that we are retrying at log level "notice". Previously we only
+      logged this information at "info", which was confusing because the
+      errors themselves were logged at "warning". Improves previous fix for
+      28614.  Fixes bug 30004; bugfix on 0.4.0.2-alpha.
