[9fans] rc and whitespaces

["Steve Simon" <steve@quintile.net>]

rc using backquote to parse strings, e.g:

	hugo% s=`{echo a b c}
	hugo% echo $#s $s(1)
	3 a
This is fine

	hugo% s=`{echo 'a b' c}
	hugo% echo $#s $s(1)
	3 a
This is also fine, a b and c are just two fields when they
enter echo but they leave the appear to be 3 seperate words.

	hugo% s=`{echo '''a b''' c}
	hugo% echo $#s $s(1)
	3 'a
This is disappointing, I was hoping that I would get
2 args and the first would be 'a b' (quotes here for
clarity, I was hoping there would be none in the assinged
variable $s

Is this what one would expect or is the text parsing
by `{ .. } different to rc's normal one - dare I say broken.

Is there a way round this?

Thanks,
