Summary: rfc822.Message() doesn't support __contains__() (+patch)

Initial Comment:
class rfc822.Message() should behave like a dictionary
but it doesn't define method __contains__() so it's not
possible to use form:

   'header' in messageInstance

attached is a simple patch that fixes this.

I've attached my own version of this patch for Py2.3.
The same solution was used for shelve so that a
single minimal intervention keeps the module
fully synced with mapping interface.  I know this
module is superceded but it doesn't hurt to sync-up
its interface for those who still use it.

Barry, if it meets your approval please reassign
back to me.
