Subject: Detached HEAD warning (again)
Message-ID: <9099EAF5-6B43-4F15-A905-9E21B45B7AE9@ai.rug.nl>

Hi all,

I strongly remember there being a discussion about this a few weeks  
ago, but I
can't find it. Basically, someone wanted to introduce a warning every  
time
someone commits on a detached HEAD. This was shot down because there  
already
is a big warning when you detach your HEAD (with which I agree).

However, someone here: http://news.ycombinator.com/item?id=538619  
pointed to
an example here: http://book.git-scm.com/5_submodules.html , which  
works with
submodules:

	$ git submodule update --init
	# sub/ is created
	$ (cd sub && touch a && git add a && git commit -am "Add new file")
	[detached HEAD 8641889] Add new file
	 0 files changed, 0 insertions(+), 0 deletions(-)
	 create mode 100644 a

	$ git submodule update
	$ ls sub/a
	ls: sub/a: No such file or directory

Now, it DOES say 'detached HEAD', but I still think this is something  
easily
missed and something that can cause a lot of confusion. Perhaps a  
warning in
such cases wouldn't hurt?
