From 01d2dce7e73e3f022d186de27dd5d15574144ca8 Mon Sep 17 00:00:00 2001 From: Michael Krelin Date: Tue, 24 Jun 2008 23:33:24 +0200 Subject: allow blob extract blobs by head/path combination If blob is invoked with no id=, it tries to look up h= and search for path= in there. Once found, proceed as normal, otherwise, fail as normal.
