Re: [Ranger-users] enhance preview script

[Liu Yubao]

Hi Hut,

Thank you for applying my patch, but I'm sorry the patch I sent
is wrapped by GMail so that you missed the "exit 0" parts for
w3m etc.

I hope for preview of html files scope.sh returns 0 not 5 because:
(1) I guess dumping html into text should be very fast thus not
     worth caching.
(2) More importantly, I often maximize and occassionally restore
     my terminal window and hope the preview in ranger can adapt
     the change of terminal geometry.

I have attached the new patch against master branch so that you
can easily apply it.

Best regards,
Yubao Liu
