Linking to a Gist seems evil to me since i make thorough (searchable) backups of my email (which would contain the code) whereas the Gist may or may not be available in a few years time. As far as highlighting goes, i'm a neckbeard who uses mu4e, so i can load up paredit mode if i want nice editing features in my compose-email pane. Having said that, i guess there are people for whom this is still a problem in 2014. On the other hand, i'd be unhappy if somebody sent me HTML email containing "highlighted" code.
