That's because your HEAD is pointing to something under refs/heads/*:
it would work otherwise.  When I'm developing on my personal branch, I
sometimes do 'git fetch origin master:master +pu:pu +next:next', and
it works as expected.  When on master branch, I can't git fetch origin
master:master and this is a cute safety feature.

Either way, I think it's a bad practice to fetch directly into
refs/heads/*: you should really be fetching to refs/remotes and then
merging your changes in.  I do want shortcuts though, which is why I'm
interested in fixing pull: there is nothing to fix in fetch as far as
I'm concerned.
