I think this could be a very nice feature.  It might be worth trying
to make this as a plugin, at least initially, because it will
introduce a new dependency (pygments I assume).  If some coordination
is required like a new hook or a way to detect which part is source
code, I'm sure patches like that would be possible to merge into the
core right away.

There's probably a few options here to try out, one as you suggest or
try just having the 'E' in red or maybe even something else.  Only
trying it will show which works better I guess.

No worries, feel free to ask questions here or on IRC.
