-      TODO: <a href="https://golang.org/cl/121055">https://golang.org/cl/121055</a>: restore 1.9 handling of missing/empty form-data file name
+      The handling of form-data with missing/empty file names has been
+      restored to the behavior in Go 1.9: in the
+      <a href="/pkg/mime/multipart/#Form"><code>Form</code></a> for
+      the form-data part the value is available in
+      the <code>Value</code> field rather than the <code>File</code>
+      field. In Go releases 1.10 through 1.10.3 a form-data part with
+      a missing/empty file name and a non-empty "Content-Type" field
+      was stored in the <code>File</code> field.  This change was a
+      mistake in 1.10 and has been reverted to the 1.9 behavior.
