If youd don't mind fetching more, you can ask just to do "git fetch".
 
But, currently:

  * A parameter <ref> without a colon is equivalent to
    <ref>: when pulling/fetching, so it merges <ref> into the current
    branch without storing the remote branch anywhere locally

I don't think it would be bad if we changed <ref> to mean <ref>:<ref>
and require <ref>: to pull without storing remote branch anywhere locally;
the problem is that we probably want <ref>:<remote>/<ref>.

An alternative would be to tag a fix, and as to do the following

  $ git fetch origin tag proposed-fix

An alternative would be to have some branch used only to bring
working directory to given state, by using "git reset --hard <ref>"
while being on it.

E.g.

  $ git checkout build
  $ git reset --hard proposed-fix

(assuming that 'build' branch was created earlier).

I rather leave warning, but (perhaps around 1.5.1) remove the
instructions. RTFM (err... I'm not sure we have one about detached HEAD).
