Is history of shell commands too short? Reflogs doesn't help
(concatenate all reflogs, perhaps preceding them with file name,
and sort by date) either?

Well, I thought of shell history also, but the problem is, that we often
have multiple repos on a machine (we may be executing a long-running
experiment in one, for example, and not want to disturb it).

Shell history in that case doesn't help.  Also, not having the branch
information is a minus (each of us puts the current git branch in our
prompt).

Fact. Although in worst case, if shell history is deep enough, you could
do forensic on it... unless you use multiple shells, freely interspersing
commands in them...
 

I didn't know about reflogs.  What did you have in mind?  Could you
show an example, please?

Unfortunately till some time ago reflogs were not enabled by default.
If they are enabled, for each branch you should have 
$GIT_DIR/logs/refs/heads/<branch> file, which contains information about
operations on given branch. It has pre- and post-operation commit ids,
and timestamp of a change, together with short description. You could
concatenate reflogs, and sort them by timestamp.

Reflogs are purely local matter, they represent local view of history.

See git-update-ref(1), "Logging Updates" section, git-repo-config(1)
(or git-config(1)), description of core.logAllRefUpdates variable,
and Git User's Manual.
