[sane-devel] Option text help

[littlesincanada]

Hi,
OK, that makes a lot of sense to me and seems like a great feature.
I came across the message when translating for the release and I thought 
perhaps I could reword it to make it clearer.
Thanks for your help.

I will have a think to see if I can come up with something appropriate 
that is not too wordy.

Cheers,
Ralph
