From d5f53d6d6f20bbd1ec5507824eb213463554b36a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 12 Dec 2009 16:00:41 +0100 Subject: [PATCH] archive: complain about path specs that don't match anything Verify that all path specs match at least one path in the specified tree and reject those that don't. This would have made the bug fixed by 782a0005 easier to find. This implementation is simple to the point of being stupid. It walks the full tree for each path spec until it matches something. It's short and seems to be fast enough, though.
