<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Comments: Allow for `comment-reply.js` to be loaded in the HTML header.
Allows for themes or plugins setting the comment-reply JavaScript as a dependency of an HTML header script. This in turn causes `comment-reply.js` to be loaded early, requiring execution to be delayed.
Props pento, peterwilsoncc, jorbin for feedback.
