However, I'm somewhat confused as to why you'd want HEAD and the 
working directory to get out of sync.

Thank you for the answer. Well, as said, it's not essential, but I was 
just now rebuilding a repo and have a few branches that I all want to be 
based on the same revision. Say, branch a, b and c, based on v2.6.20.

git clone -l -s -n <a local linux repo> local
git checkout -b v20 v2.6.20
git branch a
git branch b
git branch c

Step 1, 3, 4 and 5 of this are nearly instantaneous but 2 isn't -- this 
repo sits on a P1 with 64M of memory and a disk doing 8 M/s which is 
probably the only reason I thought asking about it was a good idea in 
the first place...

You'd be quite right in saying that there isn't much point; if I want to 
now start populating branch a, I have to "git checkout a" anyway, and 
that action _will_ now be instantaneous. If I'd replaced 2 with:

git branch --create-and-set-as-current v20 v2.6.20

then I will not have won any time until that 6th "git checkout a" step.

s/until/after/

The checkout of v20 was superfluous in this though, and I just expected 
I should be able to skip that. It fitted my mental model...
