Hi,

An insight user (yes, there are still a few of us ;-) noticed that 
insight would crash when using gdb's "search" command. Turns out this is 
a simple cleanup buglet. I think it is easier to read the patch than 
explain, so I'll leave it at that.

Ok?
Keith

	* source.c (forward_search_command): Don't fclose the stream,
	just run the cleanups.
