Having touched one C header file means that rebuilding takes almost 10 minutes here. Calling that "annoying" would be an understatement. Having multiple clones is an essential prerequsite here. > I personally am working on both branches in parallel, yes. Many > others do, too.

Which doesn't exclude that git's branching concept might be useful even here. Sometimes, at least. > But that's me, and I already know how to solve this. I'm asking what, > if anything, do we want to recommend. Among others, the switch to MSYS has made building on Windows slow down by a factor of two here (at least that's the impression I get). And I never gave bisecting a thought on my machine even before that change. In addition, recent changes to C mode has made editing C files slower by a factor of two here. So I'm hardly going to tolerate further slowdowns caused by switching branches. Mine might be an exotic case and the only useful recommendation for me is probably to get myself a new machine. Nevertheless I doubt that all Emacs users have suitable hardware that makes switching between master and Emacs-24 a feasible operation in one and the same clone. martin
