BASH bug or expected behaviour?

[Dean K. Gibson]

In GNU Bash-2.05b (Fedora Core 1), I observe the following behaviour:

If bash script A is invoked (via "source") with command line parameters, 
and bash script A invokes (via "source") bash script B with NO 
parameters specified, then the parameters specified for A are passed to 
B (rather than what I would have thought would be the expected 
behaviour, that script B is called with NO parameters).

Is this intended behaviour, or a bug?  I've worked around it by 
specifying in script A just one null ("") parameter to script B.
