Improve sage-logger

[jdemeyer]

1. Don't use the -p option at the top-level which only prints a useless [install] .

2. Use sed instead of read/echo. This preserves whitespace.

This looks good to me. It works on OS X, for example the early parts of the matplotlib log look better with this, but someone should test it on some linux machines. (I don't think this is doctested, so the patchbot won't help.)

Well, it works for me (on Gentoo Linux).

I think this is fine. I didn't mind having [install] on every line, because when you run make not every step is necessarily in install, but most of the time it's clear enough from context that it isn't needed.

I think it's a bit silly to call this a "blocker" though don't you?
