nano and color

["Bonno Bloksma" <b.bloksma@tio.nl>]

Hi,

When using nano on a Squeeze system and I open a file with name.sh I will
see color coded script Lines. When I open a file line name.xxx with the same
content there is no color coding.
On a Lenny system I never have color coding.
1) Where is this behaviour defined on my Squeeze system?
2) Can I enable it on my Lenny systems?
