Is this a bug in sh?

[Paul Hudson]

Am I just showing my ignorance of sh?
Consider the two (executable) shell scripts..

script1 is		and  	script2 is

echo $0				echo $0
name=`basename $0`		name= `basename $0`
				     ^
			Note the space here.

executing script1 prints "script1" as you would expect.  Executing
script2 prints "script2" "script2" ...... and spawns shells at an
enormous rate.

This is sunos4.0 on a sun3/50.

Go on, tell me I haven't RTFM .... ;-) Then tell me why it's this way.
