Subject: git-gui: Implement system-wide configuration handling.
X-Git-Tag: v1.6.1-rc1~3^2~11
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=153ad78b5074b37215654b1ccb59e67dc5831883;p=git.git

git-gui: Implement system-wide configuration handling.

With the old implementation any system-wide options appear
to be set locally in the current repository. This commit
adds explicit handling of system options, essentially
interpreting them as customized default_config.

The difficulty in interpreting system options stems from
the fact that simple 'git config' lists all values, while
'git config --global' only values set in ~/.gitconfig,
excluding both local and system options.
