I'm not sure either, but was curious if someone could translate the
regex into "plain language." Maybe I could observe some typical
outputs and chime in since I use R regularly? From noob-level regex
stuff, it's looking for a new line followed by some number of spaces,
a ">" and at least one period and numbers?

If I'm recalling correctly, I also noticed that babel spit out the
output from loading the rms package on the first run with :session,
but I don't think it did it with non-session. I'll have to try that
again to be sure. Re-running the block removed the package load
message.
