The fix for PR 45247 shouldn't change how the characters in URIs are escaped.

The query string portion of the URI was being dropped with [NE].  This fix ensures that the

(unescaped) query string is retained in the URI when [NE] is used.

Do you have an example of a URL which is getting escaped with your RewriteRule in 2.2.11,
but was 
not escaped in 2.2.8?  Setting the directives 'RewriteLog file-path' and 'RewriteLogLevel
9' should 
show how mod_rewrite manipulates your URI.
