Markdown support in request comments is incomplete

[aspiers]

Issue Description

At least two types of Markdown markup are not correctly supported in comments on requests, despite the UI saying "Add new comment (markdown markup supported)". Maybe others too; I didn't test.

Expected Result

In comments on requests, all types of Markdown markup are fully supported, e.g.:

• text prefixed with > should be rendered as a quote
• text indented by four spaces should be rendered as monospace

If the UI claims that markdown is supported, it should not pick and choose selected aspects to support, but rather support them all. Or maybe it's just not supported at all here; I'm not sure.

How to Reproduce

1. Go to a request with a comment
2. Click the Reply button
3. Post a comment with either > or 4 column indentation
4. Note the plain text rendering
