[development] Git best practices for client codebases

I tend to advocate full clone. You're talking about a task that version
control is designed for. Now that we've made the switch, IMO native
code:Git::bytecode:another VCS, or worse, patch stacks, etc. I don't
know what drush did before to "make this easy" - maybe pop off patch
stacks, update the module, then re-apply the patches? Fact is, though,
nothing Drush could have done under CVS can compare to patching with
native Git commits: your patches can speak the same language as upstream
changes, and you have all of Git's merge & rebase behavior at your
fingertips to reconcile them.

There are some occasional exceptions to this, but I really do think it's
a bit daft not to keep the full history. Keeping that history means
peace of mind that your patches (now commits) can be intelligently
merged with all changes ever made to that module for all time, across
new versions, across Drupal major versions...blah blah blah. Trading a
few hundred MB of disk space for that is MORE than worth it.
