Re: git switch error message tweak

To help those migrating from 'git checkout' to the newer 'git switch'
and 'git restore', this error message could be improved:

% git switch baa022666d26a5d40e86c0b6349eb7435033e80a
fatal: a branch is expected, got commit 'baa022666d26a5d40e86c0b6349eb7435033e80a'

It could print additionally

To switch to this commit in 'detached HEAD' mode, use --detach.

as long as it was indeed a commit that was given.

Excellent.

I note also that while git checkout prints a spiel about "You are in
'detached HEAD' state", git switch --detach does not. Was this
deliberate, on the assumption that if you pass --detach you know what
you are doing?

I'd say you are correct---one who passes "--detach" knows enough to
want to be in the detached HEAD state and knows enough that the
state is nothing to be worried about.
