Question about rewrite directive

[rainer at ultra-secure.de]

Hi,


a customer has this in his .htaccess file (among other things):

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)\.(\d+)\.(php|js|css|png|jpg|gif|gzip)$ $1.$3 [L]

This is to enable versioning of various files, so you can have long 
"Expires" on them and still update them as needed while retaining the 
old ones, if needed.

I want to deliver static files directly from nginx, so I created this:

     location ~* ^(.+)\.(\d+)\.(js|css|png|jpg|gif|gzip)$ {
                rewrite ^(.+)\.(\d+)\.(js|css|png|jpg|gif|gzip)$ $1.$3 ;
                expires 1h;
     }


This works in most cases, except for files which already have a version 
number of some sort.
Namely:
coda-slider.1.1.1.1452703531.js
and two others from the jquery framework.

What's wrong with my nginx rewrite?
Because in apache, the rewrite rule works as intended.

nginx 1.8.0 on FreeBSD 10-amd64.
