Looks alright.  

It was made unnecessarily harder to review because it was marked as
2/2, even though this no longer applies on top of the copy of 1/2
that was merged some time ago.  I needed to find that it was rebased
on top of 'master'; it wouldn't have been necessary if this was sent
as a single patch (with comment saying that this used to be 2/2
whose first one already graduated to 'master' under the three-dash
line).

Also re-wrapping the lines only to squeeze in "but be cautious..."
and replace s/branch/checkout/ in a few places did not help to make
it easy to spot what's changed.

This part looked a bit strange.

I think "e.g. when creating a new branch" is a parenthetical remark,
so it should be inside parenthesis.  As the last three lines in the
new text (quoted above) already warns that it may not be a branch name,
I am not sure if the "but be cautious" adds much value, though.
