Documentation: directory in which command executes

[dnebauer]

This Git::Wrapper newbie spent time untangling two Git::Wrapper behaviours to understand why git->clone wasn't doing what he expected. Number 2: I assumed from the outset that a git->clone command would execute in the directory specified in Git::Wrapper->new($dir). It wasn't until I ruled out all other possibilities that I finally questioned this assumption and realised the normal behaviour is for git->clone to execute in the cwd. The assumption I made may be peculiar to my psychology but, if it isn't, it may help other users of Git::Wrapper if the cpan/module documentation makes clear just what that initial directory is and, more importantly, is not used for, i.e., whether some/most/all commands actually execute in the cwd. These teeting problems aside, thanks for a great module.
