The Support & Abuse forms appears to be stripping out carriage returns after sending out emails but before sending data on to the Support and Abuse Ticket trackers.
See Support ticket 8979 & 9119 as examples.
I (Scott) think the problem starts here: https://github.com/otwcode/otwarchive/blob/d1858d91cfacd9b6c23d3079538bd61db2859e44/app/models/feedback_reporters/feedback_reporter.rb#L23
How to test: Submit an Abuse and Support request and make sure that formatting (italics, bold, newline, etc.) correctly show up on the Bug/Abuse trackers.
