ccollins476ad opened a new pull request #232: When pruning deps, delete dangling orphans
URL: https://github.com/apache/mynewt-newt/pull/232
 
 
   During dependency resolution, some newly-discovered syscfg values may nullify existing conditional dependencies.  If the last dependency for a particular package is removed, the package must be removed entirely from the build, as it is not actually depended on.
   
   Newt was already doing the above.  However, it failed to also check the removed package's dependencies.  If the removed package was the only dependent for a second package, the second package must also be removed. This needs to be done recursively.
   
   Prior to this fix, some orphaned packages could be incorrectly included in the build.
