FWIW, I am usually work with multiple worktrees instead of switching
branches in the same directory. That way I can have directories for both
master and release-2.4 side-by-side.

$ pwd
/Users/raimue/src/macports/base
$ git worktree add ../base-2.4 release-2.4
$ cd ../base-2.4
$ cat config/macports_version
2.4.3

See the git manual for the details:
https://git-scm.com/docs/git-worktree

The copy in base-2.4 is also configured to use a different prefix. As
the files of the build system can stay in the filesystem, I do not have
to re-configure all the time. When I want to work on release-2.4, I only
have to change directory in my shell.
