I am not sure; diff.context is rather special in that the variable
behind it belongs to the diff layer and is set via diff_config that
is called by diff_ui_config that in turn is called by log_config
which is called by format_config.
If we want to say "format.context" trumps "diff.config", then a new
internal variable to receive the value of the variable must be
invented and after the config gets read, cmd_format_patch() needs to
do something silly like this:
git_config(git_format_config, NULL);
+ if (format_context != -1)
+ diff_default_context = format_context;
repo_init_revisions(the_repository, &rev, prefix);
committing layering violation by exposing diff_default_context
variable.
