Prefer directed to neutral quotes

Prefer directed to neutral quotes in docstings and diagnostics.
In docstrings, escape apostrophes that would otherwise be translated
to curved quotes using the newer, simpler rules.

@@ -338,15 +338,15 @@ computed (i.e., non-constant) values in `sregexq' expressions.  So
 automatically quote its values.  Literal sregex clauses must be
 explicitly quoted like so:
 
-  (sregex '(or \"Bob\" \"Robert\"))  =>  \"Bob\\\\|Robert\"
+  (sregex \\='(or \"Bob\" \"Robert\"))  =>  \"Bob\\\\|Robert\"
 
 but computed clauses can be included easily, allowing for the reuse
 of common clauses:
