[PATCH 0/2] Avoid submodule overwritten and skip redundant active entries

Changes:

1. Readded the comment so the patch now shows no added lines at the comments it's 
just the previous one (As clean as I could do it).            
/*
 * If the submodule being added isn't already covered by the
 * current configured pathspec, set the submodule's active flag
*/

2. Instead of ! git config I now use test_must_fail

3. For --force used the same logic the incremental logic.

4. I also updated the docs for --force.

5. Removed the white spaces from the lines.

  submodule: prevent overwriting .gitmodules on path reuse
  submodule: skip redundant active entries when pattern covers path
