In this particular case, around the change #' is used, 
and in change ' is used.

(in some other parts in notmuch elisp source there is only ' used
-- consistency -- in one way or another, would be nice...)

emacs sharp quote   can be used in internet searches to find more info,

then, in

  Special Form: function function-object

      This special form returns function-object without evaluating it. In
      this, it is similar to quote (see Quoting). But unlike quote, it also
      serves as a note to the Emacs evaluator and byte-compiler that
      function-object is intended to be used as a function. Assuming
      function-object is a valid lambda expression, this has two effects:

          When the code is byte-compiled, function-object is compiled into a
          byte-code function object (see Byte Compilation).
          When lexical binding is enabled, function-object is converted into
          a closure. See Closures. 

      When function-object is a symbol and the code is byte compiled, the
      byte-compiler will warn if that function is not defined or might not be
      known at run time. 

  The read syntax #' is a short-hand for using function.
