Perhaps with a cron job running a script every minute or so.  You'd want
to verify that changes actually took place before attempting a commit.
Also, what log messages would you be providing?  Log messages can be
very important to the context of a change and the ability to later find
them.

If you're using a specific application, such as a Wiki, it may work
nicely, as log messages can be easily gleaned, and many offer post-edit
hooks that you could use to invoke git.

You may want to use StGit as that may allow you to make such lightweight
commits easily while still allowing reordering, etc., though I am not
familiar with that application porcelain.

Obviously, my final caution is that while this is possible with some
configuration, you may lose valuable "signal" information in the "noise" of
commits that such a continuous operation might incur.  This low SNR may
make it more difficult to find and revert changes you didn't actually want
to happen or to glean a meaningful history of your working tree.

While in the operable borders of Git, it's outside the normal usage patterns.
If you have success, let us know how it worked for you.
