Why do you think "raw" mode for %hist is not an improvement? There was
a bug a while ago that screwed up the numbering, but it's fixed now.
Overall, I think it's better to have the default behaviour that has as
little "clutter" as possible (_ip.system etc.).

Justification in this particular case is that %hist is an interactive
command, and as such unlikely to break scripts. In most "daily usage"
scenarios it should be a net win. I'm reluctant to talk about
"backwards compatibility" when we are dealing with interactive stuff.

I am not opposed to adding -t as default option to %hist in ipy_legacy.py.

I had no intention of breaking the profiles; in fact, after a hurried
svn up at work I thought it was a new file (even as only the profile
was new).
