Formatting labels used for URL buttons in Gnus articles

[Narendra Joshi]

Hi,

A lot of email that I get has very long URLs in the text 
version. I use `gnus-treat-buttonize' to convert those to 
clickable buttons. The labels are usually very long and I would 
like to use something like `gnus-shorten-url' to have a smaller 
string displayed as the label of the button. Any pointers to how I 
can achieve this would be great. 

Thanks,
