Cleaner change log when releasing package from multi-package repository

[davidlatwe]

When releasing package from a Git repository that contains multiple packages, the change log will include commits that are not related to current package.

So, what do you think about changing this

https://github.com/nerdvegas/rez/blob/eef7523a53ab6d34ccdb6e088bf6af94a3f51297/src/rezplugins/release_vcs/git.py#L155-L161

into

 if prev_commit: 
     # git returns logs to last common ancestor, so even if previous 
     # release was from a different branch, this is ok 
     commit_range = "%s..HEAD" % prev_commit 
     args.append(commit_range)

 args += ["--", "*"]  # only files under current working dir
 stdout = self.git(*args) 

With this change, git log -- * should only take commits that are related to files under current working dir (the package root), and the package change log should be clearer.

Also, appending -- * after git diff-index command here

https://github.com/nerdvegas/rez/blob/eef7523a53ab6d34ccdb6e088bf6af94a3f51297/src/rezplugins/release_vcs/git.py#L122-L129

Will allows you to release package without being stopped from uncommitted changes that aren't related to current releasing package in multi-pkg repo.

So I have implemented a release_vcs plugin for this, if anyone is interested, it's here https://github.com/davidlatwe/rez-kitt
