Download of Linux install shell script

[Nick Payne]

I have noticed that the last few versions of the unstable Lilypond 
releases, if I just click on the download link (eg 
http://download.linuxaudio.org/lilypond/binaries/linux-64/lilypond-2.17.11-1.linux-64.sh), 
then instead of a dialog asking for the location to place the download, 
the script file opens as a web page. I have to right-click and choose 
"Save link as..." to download it. The behaviour used to be that the 
default was to download, and other shell scripts that I download from 
other sites (eg 
http://download.racket-lang.org/installers/5.3.2/racket/racket-5.3.2-bin-x86_64-linux-debian-squeeze.sh) 
still default to downloading when clicked, so it would seem that the 
change in behaviour is at the server end and not on my machine.

I'm running Chrome on Linux Mint amd64.
