+2.	Made restore to chdir() back into the initial directory when
+	dumping core while aborting a comparision operation. The
+	previous behaviour was to write the corefile at the root of
+	the directory being compared, which could very well be 
+	read only and preventing the corefile generation. Thanks
+	to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
