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

Changes:
1. Test now has an explicit error message in patch 1 
2. Nice catch on the double function calls those were not needed 
   a single function call to git_config_get_string_multi did get job done.
3. While I am at it also fixed some indentation issues (Only hoping i didn't create any unknown ones)
and localized the loop variables.

K Jayatheerth (2):
  submodule: prevent overwriting .gitmodules on path reuse
  submodule: skip redundant active entries when pattern covers path
