Allowing regular expression in --allow-root option

[Christian BAYLE]

This is not a bug, but as my message was rejected by the dev list
with recommendation to send there 
I do it

I found this patch that allow the use of regular expression with 
--allow-root option
These have been done by Gavin Walker
I find this usefull
Can this be added in cvs?
