[Basil L. Contovounesios]

I don't use sieve scripts, but I noticed a minor nit in your patch:

In both hunks, 'message' is given an arbitrary string as its first
argument.  Any objections to the following cleanup of sieve.el text
formatting code?

Subject: [PATCH] Tidy up sieve.el text formatting

* lisp/net/sieve.el (sieve-edit-script, sieve-upload): Do not pass
arbitrary string as first argument to 'message' (bug#25764).
(sieve-help): Split long string across multiple lines.
(sieve-refresh-scriptlist): Use ngettext.  Fix grammar.
