    I'd prefer it if you (and everyone else) could give a meaningful
    English-language Subject: to patches, please.

    A well-chosen patch Subject: becomes a sort of globally-unique key by which
    the patch is tracked - I munge it into a patch filename and it propagates
    all the way into bitkeeper. It can be used for searching email folders,
    googling, inter-developer discussion, etc, etc.
