Submodule's .git file contains absolute path when created using 'git clone --recursive'

Hi,

According to git-clone man page - running 'git clone --recursive' "...is equivalent to running 'git submodule update --init --recursive' immediately after the clone is finished...", though I found a little difference between the two regarding the submodule's .git file:

1. Running 'git clone' and 'git submodule update --init --recursive' 
separately will create the .git file in each submodule containing a relative 
path to the superproject's .git directory as expected.

2. Running 'git clone --recursive' will create the .git file containing an 
*absolute* path to the superproject's .git directory. (as it was expected 
using git versions 1.7.8 - 1.7.10 as far as I understand)

Not sure if that's a bug but it got stuff behaving really weird in a specific usecase on one of our environments. It would be highly appreciated to update the docs at least.

Thanks.
