From dac529e44fb9e8c0ee4628c0f947db8890950317 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Tue, 10 Apr 2012 07:30:22 +0200 Subject: [PATCH] check_refname_component(): return 0 for zero-length components Return 0 (instead of -1) for zero-length components. Move the interpretation of zero-length components as illegal to check_refname_format(). This will make it easier to extend check_refname_format() to also check whether directory names are valid.
