Of course you've never screwed up a repository using git commands,
right? I've messed up plenty. A good way to mess up a repo is to get
the data in .git/* out of sync with what is in the repo. I'm getting
good enough with git that I can fix most mess up with a few edits, but
it took me two years to get to that point. Rolling back to a check
point is way easier. User error and a command failing are both equally
valid ways to mess up a repo.

The reflog contains all your check points, for every modifications you
make, even the stupid ones.  You should look at it.

The state contained in the other config files in .git/* is not getting
check pointed. I can use reflog to move my branch heads around. But
doing that does not undo the changes to the state recorded in .git/*.
After the error I encountered  I moved my branch head back, but the
state stgit had stored in .git/* was out of sync with where the branch
had been moved to.

It's up to stgit to version control its state then.  It may even use a 
reflog for it.  All the machinery is there already.
