ccollins476ad opened a new pull request #141: Initialize and update submodules after checkout.
URL: https://github.com/apache/mynewt-newt/pull/141
 
 
   Always initialize and update submodules on checkout.  This is necessary for repos that contain submodules.  Without this change, such repos can be left in a modified "(new commits)" state immediately after switching branches.  If the submodules have already been updated, this does not generate any network activity.
   
   For example, before this commit, when I try to install version 1.1.0 of mcuboot with `newt upgrade`,
   
   ```
   [ccollins@ccollins-mac:~/tmp/myproj3/repos/mcuboot]$ git status
   On branch v1.1.0
   Changes not staged for commit:
     (use "git add <file>..." to update what will be committed)
     (use "git checkout -- <file>..." to discard changes in working directory)
   
           modified:   sim/mcuboot-sys/mbedtls (new commits)
   
   no changes added to commit (use "git add" and/or "git commit -a")
   ```
   
   Subsequent update operations will fail due to the local modifications.
