Fair enough, but the browser can update the highlighting if it is told
(after execution) that it is a %%bash cell. So, after execution, the
highlighting would look OK (much like after rendering markdown looks like

Each chunk can be thought of as a cell. In the console, a chunk would be
either one line or a multiline input, much as cell magics work in the
console right now.
Some frontends could use the metadata associated
to that chunk, others might not.
I don't know the internals of the console that well, but how different is
it to the logic
in Min's test script for a notebook (https://gist.github.com/2620876)? If
goes through something like line 32 in that file, then it seems like it is
reasonable to have
a msg that is a "metadata" for that last execute request. This script has
no notebook, but I would be happy
if I could send the iochannel some metadata (via the shell channel) for the
last execute request.
What would be needed is for the execute request to generate some "metadata"
