[PATCH 0/2] Submodule harden fetches (WAS: submodule: Fetch the direct sha1 first)

A simple patch evolves into a series!

First we'll fix a bug by adding the --objects switch to rev-list to have a stricter check for the desired commit to be there. IIUC this is not 100% right yet, but it improves the situation.

The second patch introduces an extra fetch in case the first fetch did not yield the expected commit, using the pattern

    # first 4 lines unchanged:
    if $sha1's history and objects are incomplete:
        fetch ;# normally just like we have done before
    else 
        die ...
    # new code:     
    if $sha1's history and objects are still incomplete:
        fetch $sha1
    else
        die ... 
        
Thanks,
Stefan
