Howto request: going home in the middle of something? v2009

[Patrick Doyle <wpdster@gmail.com>]

Hello,
I've developed a work habit of keeping my source code repository on a
USB stick and carrying that back and forth with me between work and
home.  (I typically have small, branchless, single-developer
projects.)  When I arrive at the other machine, I do

$ git pull
(code, commit, code, commit, etc...)
$ git push

Occasionally at the end of the day (if I'm at work) or at the end of
the night (if I'm at home), I'm in the middle of something that I want
to continue, and I end up making a "work-in-progress" commit

$ git commit -a "WIP"

just so I can pull that in the next day/evening and continue where I
left off.  But that leaves a bunch of "WIP" commits in my history.  I
started looking around for a better way to do this, and came across a
2007 discussion (at
http://kerneltrap.org/index.php?q=mailarchive/git/2007/10/18/347020/thread)
where the OP really wanted (as do I) do be able to do something like
this:

$ git stash
$ git push
$ git stash-push
(travel to other site)
$ git pull
$ git stash-pull
$ git stash apply
(continue coding and committing as before)

There were a number of different suggestions, such as:

$ git commit -b temp -a -m "Hold for transport home"

Then when I get home I do this:

$ git fetch work
$ git merge work/temp
$ git reset HEAD^
 # code code code
$ git commit -b temp -a -m "Hold for transport to work"

When I'm finished at home and want to carry on at work:

$ git fetch --force home
$ git merge home/temp
$ git reset HEAD^
 # start coding for the day

... or using git-bundle

That discussion dates back to 2007.  Is there a new, improved, 2009
way of accomplishing this?
