persistent xss possible - requires commit access

Bug Description

Binary package hint: gitweb

I am reporting a persistent xss vector in gitweb, note this requires a
user to have commit access to a repository that gitweb is configured
to display. The vector is the fact that gitweb "serves" up xml files -
which can (just as gitweb does) embed html that could be used to
perform a cross-site scripting attack.

e.g. (lol.xml).
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
<html xmlns="" xml:lang="en-US" lang="en-US">

and viewed at http://$HOSTNAME/$PATH_TO_GITWEB/?p=lolok;a=blob_plain;f=lol.xml

The requirement on commit access for this to be an issue vastly reduces the impact and severity of this issue.
