Is that correct? I'd assumed that functions do execute in the current
shell since you can alter variables from a function, whilst you can't
from a "()".
e.g.
--------------------------------------------------------------------
$ cat /tmp/foo
#!/bin/sh
f (){
x=2
}
x=1
f
echo $x
( x=3 )
echo $x
--------------------------------------------------------------------
$ /tmp/foo
2
2
