A note on your post -

When you write the post in HTML and then rely on your e-mail
client to create a plain-text version, the usual result is
garbage-text, unusable by the patch program.

Please author your post as plain text to begin with.

This mailing list prefers a plain-text file (makes it easier
to review, both now and in the archives).

If using an e-mail client that you can't control enough to
ensure a plain-text post, at least attach the plain-text file.
