[PATCH] Look at both unpacked and packed objects for short name expansion

From: Johannes Schindelin <johannes.schindelin@gmx.de>
Date: Sep 15, 2005, 23:21 UTC
Message-ID: <Pine.LNX.4.63.0509160120470.3859@wgmdd8.biozentrum.uni-wuerzburg.de>

We used to check for a unique expansion in the unpacked objects, and if one was found, we forgot to check in the packed objects, too.
