Pull requests from github

I am trying to update gmoccapy from 1.5.8 to the latest version. I could not find any instruction beyond "pull from master" so this is not very helpful. Downloading files from the repository using wget result in useless HTML files. I can download them in raw format but have no idea where to put them. Using git clone results in the following:

git clone github.com/LinuxCNC/linuxcnc/tree/master...mc/usr_intf/gmoccapy src
Cloning into 'src'...
remote: Not Found
fatal: repository 'github.com/LinuxCNC/linuxcnc/tree/master...c/usr_intf/gmoccapy/' not found

I can usually figure stuff out eventually, but this one has me stumped. I'd appreciate any help. Thanks.

When I go to github.com/LinuxCNC/linuxcnc/tree/master...mc/usr_intf/gmoccapy, there is no "clone or download" button. I'm probably at the wrong location. Not to worry though. I managed to build the latest master version although I didn't really want to build the entire kernel and rt patch but it's done now and working well. On to the next problem.
