Revision: 9065
Log message:
Addressing buf #573.
The current mode is a relaxed policy, where array elements
are glob-expanded, but are otherwise individual words.
Also, be much more careful about selecting environment
definitions in command-line parsing. Before, we would fail
on definitions like the following.
A = a
B = b
$A$B=foo ls
This would have failed with
ab=foo: command not found
This is fixed by more agressive flattening of the command
line before environment parsing.
