I only spent about 5 minutes looking for this, so I could be totally
wrong:

In 0.8.53, src/http/ngx_http_parse.c:1220 appears to be the start of the
relevant code.  On a quick scan, it looks like the percent-decoding is
hardcoded.  (case sw_quoted, followed by case sw_quoted_second, inside a
switch loop)

Again, I am not too familiar with this source and only spent a few
minutes looking.  So someone please correct me if I am mistaken.
