From dad2586a6b30da902d5f1979221eccc474425a7a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 14 Jul 2013 15:35:35 +0700 Subject: [PATCH] parse_pathspec: support prefixing original patterns MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This makes 'original' suitable for passing to an external command because all pathspec magic is left in place, provided that the external command understands pathspec. The prefixing is needed because we usually launch a subcommand at worktree's top directory and the subcommand can no longer calculate the prefix itself. This slightly affects the original purpose of 'original' (i.e. reporting). We should report without prefixing. So only turn this flag on when you know you are about to pass the result straight away to an external command.
