strange thing in ` `

[eric%cit-vax at sri-unix.UUCP]

The command 
	echo `echo '"[hello there]"'`
prints

there]"

instead of the expected 

"[hello there]"

The stuff inside the ` ` can be anything that prints
out "[hello there]" (with the double quotes). What is going on?
Where did

"[hello

go? This is in the C shell. The shell does the expected thing.
