Feature request: Add html anchors to line numbers in file view

[GoogleCodeExporter]

When posting gitiles file-view URL's into bug reports, it would be very nice to 
be able to link to an html anchor for the exact line I'm interested in.  
Something like:

https://gerrit.googlesource.com/gitiles/+/master/gitiles-war/src/main/webapp/WEB
-INF/web.xml#line20

Ideally, the html might look like this:

<li class="L9"><a name="line20"><a 
href="#line20"><span>...</span></a></a><br></li>

The <a href="#line20"> is just to make it easy to right-click and "Copy link 
address"

I don't want to fork prettify.js, and eventually I want to move to CodeMirror. 
But I think in the meantime it wouldn't be hard to do this by postprocessing 
every <li> within the <pre class="prettyprint">. Not sure what the performance 
impact would be (though considering we may already show a flash of unstyled 
<pre> this may be ok).
