Preview .patch file links in markdown comment
If someone attaches a patch file to a comment, it'd be handy to be able to preview it inline. If I am reading comments (example) and want to quickly see what's in the patch, currently I have to download it and open in text editor, and later delete the file.
Proposal
Add a Preview button next to links to .patch files. On click, download file contents and display in a code block with diff syntax highlighting
