+ * The commands in the "log/diff" family have had an FILE* pointer in the
+   data structure they pass around for a long time, but some codepaths
+   used to always write to the standard output.  As a preparatory step
+   to make "git format-patch" available to the internal callers, these
+   codepaths have been updated to consistently write into that FILE*
+   instead.

+ * One part of "git am" had an oddball helper function that called
