Subject: playground refactoring: Dgit.pm: Expose $local_git_cfg
X-Git-Tag: archive/debian/4.1~39
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=dgit.git;a=commitdiff_plain;h=d99fbfc09e25cda5a7e95c3c632436d22cb4e59a;hp=3c79424dd5982b8bea141a14e1909a972de0f2cc

playground refactoring: Dgit.pm: Expose $local_git_cfg

This is now the default for playtree_setup.  The caller can simply set
it explicitly.

We make this part of a new :playground export tag for Dgit.pm,
which is going to gain other bits shortly.

And, we add some comments, and move the global; more code and
commentary will appear around this.
