No, at least Emacs and glibc have maintenance
In Emacs some patches are applied to the emacs-23 branch,
and someone occasionally merges them into 'master'. A 'pending'
branch holds patches waiting to get into 'master'. But
the 'pending' branch is rarely used (two changes since
July) and the emacs-23 branch is strictly for the old
release. The main development is all in 'master'. After
Emacs 24 comes out, a new emacs-24 branch will be created
In glibc there is a separate branch for every release,
and as I understand it these primarily cherry-pick fixes
back from 'master'. The main development is on 'master'.
