The detach-HEAD idea does all these things, but rather:

- There's no need to tell newbies anything
- It don't just reduce the frequency of the problem, it eliminates it

:-) Also,

- You eliminate the problem of git thinking the working copy came from a
  revision it didn't come from, and thus eliminate the "any commit will
  now overwrite the push" problem
- You can still write hooks to update the working copy if you like
- It's completely intuitive to anyone coming from Mercurial (and it's these
  people who are going to be doing the pushing into non-bare repositories,
  because that's the workflow they're familiar with)

It might also be a good idea to print a warning about the working copy needing
to be updated or else committing changes will create a branch. That seems
obvious, and if you're pushing into a checked out branch, you probably know that
though.

Johannes is apparently fed up of trying to explain to me why people want their
working copy associated with the wrong revision so that their commits will
overwrite the pull. ;-) If anyone else cares to give it ago I'd appreciate it,
since I still don't see the utility.

Hoping Johannes has a sense of humour...
