I'll really apreciate a tool that does not make me waste those 20

It's true that bzr is appreciably slower than git doing common
operations: diff and annotate is intantaneous in git (on GNU/Linux),
takes a few seconds on bzr. But when I screw my git setup, the time that
takes me to fix it is much longer than the time I lost waiting for bzr.

And this is different from other VCSs how?

The typical Emacs developer is not like Torvads. Emacs has a development
style that is very far from Linux's. Every example about how well git
works specifically for Torvalds is moot.

git's mergin strategies are possibly superior to bzr, but do we (Emacs
and most other Free projects) really need them? I think not.

This will be fixed over time. git's problems (mostly UI and poor support
for non-POSIX environments) will not be solved anytime soon.
