Comment (by conner_bw):

 Ok. I messed around with this. I think I have something.

 Instead of changing the rewrite rules, Change:

 {{{
     RewriteCond %{REQUEST_FILENAME} -f [OR]
     RewriteCond %{REQUEST_FILENAME} -d
     RewriteRule ^ - [L]
 }}}

 To:

 {{{
     RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
     RewriteCond %{REQUEST_FILENAME} -f [OR]
     RewriteCond %{REQUEST_FILENAME} -d
     RewriteRule ^ - [L]
 }}}

 This works by checking internal Apache variable %{ENV:REDIRECT_STATUS}.
 This variable is empty at the start of rewrite module but is set to 200
 when first successful internal rewrite happens. This above condition says
 bail out of further rewrites after first successful rewrite and stops
 looping.
