REVISION SUMMARY
  Most uses of Content::RemoveHeader() do not check its return value;
  they want to remove the header if it is present, but don't care if it
  isn't.  This change silences the unnecessary compilation warnings.

REPOSITORY
  R180 PIM: KMime

BRANCH
  removeHeader (branched from master)
