Dear all,
The Sage-Combinat patches should now apply on 4.5.1 and 4.4.4. Please
report if you encounter any issue!
Thanks Nicolas for rebasing your patch! I micro-fixed the guards, and
further guarded out Mike's patch, and a couple others depending on it

I use both clone and queues: if I'm working on multiple projects
simultaneously I would prefer to have a clone for each instead of just using
queues. This is especially important if some of my patches touch low level
.pxd files (e.g. sage/structure/element.pxd): I really don't want to be
pushing
Oh, yes, I see: sage -b does indeed only build changed files and
their dependencies; I must have been working on a quite fundamental

Done: trac #9673 (http://trac.sagemath.org/sage_trac/ticket/9673). I
asked for clear semantics of the -tnew flag, but from Simon's reply,
this answers my question. Wouldn't it make sense, then, to have a flag

If the [...]m syntax is messing too much with Python's syntax, don't
