[RFC/PATCH 0/6] Git submodule: 'foreach' enhancements and nested submodule handling

Hi,

This patch series attempts to expand 'git submodule' command in two regards:

1. Clean up, selftest, and enhance the 'git submodule foreach' command.
2. Provide better handling for nested submodules where the user want to
   operate on _all_ submodules simultenously.

The first 3 patches in the series are fairly trivial and straightforward. The last 3 patches are slightly more RFC in nature, although their implementation is still fairly straighforward.

Patch 3/6 is a resend of a patch that I sent stand-alone on 2009-08-16.

Have fun! :)
