Another point: Please do not link attachments directly but put there the
URL to your mail, so gets access to the whole message. It will further
help Wine developers to quote the subject too, so they might remember
the patch without clicking the link at all. In this case, it might look
like this:

previously sent patch: "shlwapi: If the URL_UNESCAPE_INPLACE is set,
UrlUnEscape should not fail if pcchUnescaped buffer is
NULL" (http://www.winehq.org/pipermail/wine-patches/2008-August/059445.html)

PS: Please don't be offended by this kind of critique. I appreciate the
work you do for Wine, and would like your patches to go in, so I am
trying to give hints to you how to make your patcher easier to review to
raise chances of getting your patches committed.
