How to refer to a code snippet in email?

[Drake Talley]

There is ample documentation for how to include a patch file, commits, or diff in emails,
but I haven't been able to discern what is the preferred way to refer to code snippets
as line ranges in a file for a given revision.

Is this just not that common so it isn't done?  Or is there a general approach
to just pasting in a hunk of source code and manually stating the file/line numbers?

Curious both as to what's possible in an email-driven git workflow and how things are done here.


Thanks!
