bug#43634: 27.1; Wrong indentation in sieve-mode

[Unknown]

Copy the following Sieve script to "sample.sieve":

if size :over 100K {
  reject "I'm sorry, I do not accept mail over 100kb in size.";
}

M-x mark-whole-buffer and indent. The closing brace is reindented in a
strange way:

if size :over 100K {
  reject "I'm sorry, I do not accept mail over 100kb in size.";
         }

As sieve-mode inherits from c-mode, putting things in parens works, but
this is not valid according to the grammar (see
https://tools.ietf.org/html/rfc5228#section-3.1):

if (size :over 100K) {
  reject "I'm sorry, I do not accept mail over 100kb in size.";
}

I guess there isn't really much in Sieve that's that C-like.  I mean,
it's {} and strings, but ...  not the whole shebang.

Do we have a simpler mode somewhere that just understands {} and strings
that Sieve mode could inhering from instead?

Apparently not (except just calling smie, which didn't quite do the
right thing), so I just took an indentation function and altered it
slightly.  Fix in Emacs 28.
