This option can be used to setup the user.name and user.email git-config
options within each new git repository cloned or installed from
snapshot, including kde-projects repositories. This can be useful for
KDE developers with multiple Git identities that they use for
development.
Module settings override global settings so you could e.g. have a global
git-user option for KDE modules and then override specific modules or
module-sets with a different git-user setting.
This setting is only applied during the initial git-clone process
though... if there's interest in having kdesrc-build re-apply settings
later that's possible too.
