Comment (by jrfoell):

 I confirmed that the Ron Rennick / Pippin suggestion did not work for me
 on Apache 2.4.6 (added to a fresh WP 3.8.1 multisite subfolder install).
 The following seems to work, but it is not elegant and I haven't
 determined if it has other adverse effects:

 {{{
 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^ - [L]
 # start new
 RewriteCond %{REQUEST_URI} ^/wp-(content|admin|includes).*$ # look for
 beginning slash
 RewriteRule ^ - [S=2] # skip to index.php
 # end new
 RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
 RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
 RewriteRule . index.php [L]`
 }}}

 The key is really noticing the difference between "wp-
 content/uploads/2013/10/test.jpg" and "/wp-
 content/uploads/2013/10/test.jpg" - with or without a beginning slash - so
 Apache doesn't go looking for a file outside of the webroot.

 Some of this seems to go against the documentation regarding "Per-
 directory Rewrites" found here:
 http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule
 specifically the second-to-last point:

 `The removed prefix always ends with a slash, meaning the matching occurs
 against a string which never has a leading slash. Therefore, a Pattern
 with ^/ never matches in per-directory context.`

 But I could be reading it wrong.
