OK, so it's not a bug, but I see a handy feature to be
added later here.
If I have a function:

foo() 
{
	if [ -d $whatever ]
	then
		cd $whatever
	else
		exit
}

This will exit from the shell, not the function only. How can
I exit from just the function.

Also, using bash-1.03 with the vi diffs that came accross
the other week, on an xterm, I have problems with the
command line editing. 
	1) it doesn't know where the beginning of the
	   line is.
	2) I have CTRL chars embedded in my PS1 to reverse
	   video it on the xterm, & this confuses bash.

Use "return".
