I recognize most people will prefer to have the .git directory separate.
And I do not intend to make this option the default.
My reasons are:
- As it is not clearly stated in the doc that the gitdir is separate.
The first time I have copied one module to an USB key I had a big
surprise.
- This will not change anything for people not using it.
- I use an other patch which I plane to send later which enable multiple
level of superproject to add a gitlink to the same submodule.
And in this case the superproject containing the separate gitdir will be
arbitrary and depend on the processing order of the
'git submodule update --recursive' command.
- I have written this for myself and have using it since 2012 and send it in
the hope it could be useful for someone else even if it is only a few
people. But if its not the case no problem I will keep using it for myself.
