From e24317b4d093e4b148996172d0b749f09a0e6f2e Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 26 Oct 2005 01:43:03 +0200 Subject: [PATCH] Test in git-init-db if the filemode can be trusted ... and if not, write an appropriate .git/config. Of course, that happens only if no config file was yet created (by a template or a hook).
