Well, this can also be parameterizable. Indeed, show_log and log
formatters are not far from what I want. Except that I'd want the log
formatter to be sending an email instead of printing something to
stdout.

I didn't try writting a log_formatter not doing log formatting, but
this might work (then, this is a matter of naming, I don't want
show_log to do something else that showing the log normally...).

I've posted my draft branch here if someone's interested in having a
look at it.

(this is the one containing an ugly cut-and-paste from log.py)
