From c0885435537e4b93709d2bf39ce36454186057a1 Mon Sep 17 00:00:00 2001 From: Rene Scharfe Date: Fri, 25 Jul 2008 12:41:22 +0200 Subject: [PATCH] archive: move parameter parsing code to archive.c write_archive() in archive.c is the only callsite for the command line parsing functions located in builtin-archive.c. Move them to the place where they are used, un-export them and make them static, as hinted at by Stephan.
