For better or worse, git also includes a command "git-rebase" that can
collapse such micro-commits into a larger one.

Quoting the git-rebase man page:
A range of commits could also be removed with rebase. If we have the
following situation:
E---F---G---H---I---J topicA
then the command
git-rebase --onto topicA~5 topicA~3 topicA
would result in the removal of commits F and G:
E---H´---I´---J´ topicA

While I wouldn't recommend using this for historical revisionism, I
imagine it could be useful during code-review time when the
micro-commits (from both the patch submitter and patch reviewer)
are interesting. After the review, the commits could be collapsed
into meaningful-sized-chunks just before they're merged into the
official branches.
