From b48cbfc5e6112952bc3be4dea0208bc5e1f331eb Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 30 May 2017 01:17:42 -0400 Subject: [PATCH] version: convert to parse-options The "git version" command didn't traditionally accept any options, and in fact ignores any you give it. When we added simple option parsing for "--build-options" in 6b9c38e14, we didn't improve this; we just loop over the arguments and pick out the one we recognize. Instead, let's move to a real parsing loop, complain about nonsense options, and recognize conventions like "-h".
