If you are thinking about 'linux-next', it is exception rather than the rule.

Besides, Git is feature rich and allows many different workflows, so you should _always_ read the Development/Contributing document for specific project, if it exists. (See also explanation below on different workflows).

First, there isn't just _one_ way to deal with non fast-forward (rebased) branch; there are many possible workflow wrt rebasing.

There can be something like 'pu' (proposed updates) branch in git 
repository, which is basically read-only, rebuild from scratch merging 
branch gathering topic branches which are not ready yet for 'next'
(for development branch), like work in progress and the like.  It is 
here to be able to view/examine those topic branches, without crowding 
public branch namespace.  In short: it is only to view.
Workflow:
  $ git fetch origin   OR   git remote update

Then there is something like 'linux-next' tree, which is also rebuild 
from scratch, and as far as I understand serves as gathering point for 
different patches being prepared to enter Linux, and to resolve 
conflicts early.  It is, if I understand correctly, to check if it 
compiles and doesn't have bugs, and to test merging your work; _not_
to base your own work on.
Workflow:
  $ git fetch origin   OR   git remote update
  $ git checkout origin/master  # detaches HEAD / not on any branch

Finally (or not: perhaps there are yet different workflows involving
history rewriting) there are projects which use rebase based workflow.
The information about it should be on project homepage (or wiki).
Workflow:
  $ git pull --rebase  # or configure it: branch.autosetuprebase etc.

Second, this is open source. If you feel that documentation needs improvement, now that you have all this information, you can simply send patch either to manpages, or to Git User's Manual. Trolling won't work ;-P
