BUG: Add HOME to the git environment.

[rkern]

git config files can contain ~ expansions that require $HOME to be defined.
Some installations of git have these in the global defaults now.

Before:

~/git/numpy master
❯ cat /usr/local/etc/gitconfig
[include]
    path = ~/.gitcinclude

[credential]
    helper = osxkeychain

~/git/numpy master
❯ python setup.py --version
error: could not expand include path '~/.gitcinclude'
fatal: bad config line 3 in file /usr/local/etc/gitconfig
error: could not expand include path '~/.gitcinclude'
fatal: bad config line 3 in file /usr/local/etc/gitconfig

  "details." % self.metadata.version
1.13.0.dev0+

After:

~/git/numpy fix/git-home
❯ python setup.py --version
1.13.0.dev0+c0be995

LGTM

I have no idea what this does. What is ~/git/numpy?

[njsmith]

@charris: I think he has a fancy multi-line command prompt, where ~/git/numpy is showing the current directory where he runs the command (and master and fix/git-home are the current branch).

[rkern]

Yes, fancy zsh prompt.
