From b48158ac94cf725834b70b4a5ab7f2d152a741d4 Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Sun, 3 May 2015 20:00:00 +0530 Subject: [PATCH] cat-file: make the options mutually exclusive We only parse the options if 2 or 3 arguments are specified. Update 'struct option options[]' to use OPT_CMDMODE rather than OPT_SET_INT to allow only one mutually exclusive option and avoid the need for checking number of arguments. This was written by Junio C Hamano, tested by me.
