Damn - so it turns out that the only way to tell if a hash is inside 
quotes or a comment marker is to parse the string fully. As most of the 
parsing (pulling out list values with or without quotes etc) is done 
inside validate it would be 'inconvenient' to move this inside ConfigObj.

This is because configspecs actually have a slightly different syntax to 
normal ConfigObj - even with 'list_values' set to False this is invalid 
syntax:

    name = string(default="#ff00dd")

You can actually get round this by using triple  quotes:

    name = '''string(default="#ff00dd")'''

Slightly ugly but it works. I'm working on a longer term fix where 
ConfigObj won't parse comments in configspecs - and let validate remove 
them instead (implementing support for comments in validate itself).
