Sorry, I did not follow the thread(no email for a while)
so I maybe out of line.

Normal behaviour, $source was expanded already

Normal behaviour source is set in the environment , but have you try these
# source='hello' ; sh -c 'echo $source'

# export source='hello' ; sh -c 'echo $source'
hello

different behaviours (note the export).

Well that expected behaviour

# source='hello'  echo $source

$source was already expanded,  But If you try this

# cat echo_source
echo $source
# chmod +x echo_source
# source='hello' ./echo_source
hello

I do not know if this was helpfull, not seeing the original question
I shall go back to the shadow.

Note: the examples were done on my Solaris box with bash 2.02
