[PATCH] Fix make_absolute_path() for parameters without a slash

From: Johannes Schindelin <johannes.schindelin@gmx.de>
Date: Mar 2, 2008, 07:17 UTC
Message-ID: <alpine.LSU.1.00.0803020717060.22527@racer.site>

When passing "xyz" to make_absolute_path(), make_absolute_path() erroneously tried to chdir("xyz"), and then append "/xyz". Instead, skip the chdir() completely when no slash was found.

	I should add a test, but I am simply too tired now.  Will do so 
	tomorrow.
