It seems that if the PR diff contains text wrapped in < and >, the text is not displayed, as the browser thinks this is an HTML tag.

A user of the Pagure instance I run submitted a PR that contain a comment like # Author: Someone <someone@somewhere.com> and the <someone@somewhere.com> part doesn't show up when seeing the PR diff (it is in the page source though, marked as an invalid HTML tag).
# Author: Someone <someone@somewhere.com>
<someone@somewhere.com>
It seems to be fixed already in staging: https://stg.pagure.io/bodhi/pull-request/2#request_diff
