show-branch: take default arguments from configuration file.
This lets showbranch.default multivalued configuration item to be used as the default set of parameters to git-show-branch when none is given on the command line. I keep many topic branches (e.g. zzz/pack, net/misc) and branches used only as a reference under subdirectories (e.g. hold/{html,man,todo} track the same from git.git, but clutters the show-branch output when shown along with the main development; ko/master tracks what I have pushed out already and refetched from the kernel.org server), and often run: $ git show-branch ko/master heads/* to view only the ko/master head and branches I keep immediately under $GIT_DIR/refs/heads. With this change, I can have this in my $GIT_DIR/config file: [showbranch] default = ko/master default = heads/* and say $ git show-branch Signed-off-by: Junio C Hamano <junkio@cox.net>
