Seems a good idea, I've made a patch based on yours that does this for
those three methods.  [There are probably other places this happens too]

Change applied in SVN r10987:

Incidently these in-line patches are hard to deal with, something seems
to be doing something with the spaces or line endings.  I think they are
better as an attachment in email (or a file upload with a bug report).

Thanks for the patches.
