Set bash's shell option nullglob by default?

[Roman Rakus]

Hi,
I have a question about nullglob bash's shell option. I want to hear 
opinions.
The behavior is nicely described in bash reference manual [1]
By default, the nullglob is turned off. And it tends people to use bad 
habits in shell scripting.
In my POV the nullglob could be turned on by default. However, i would 
like to hear opinions from others.

It is possible it can break many scripts even in rpm's scriptlets, but 
as I already said, it's because bad habits. So the main gain will be the 
people will learn how is the globbing in bash and in the whole 
environment working.
