diff:groovy: can't clone checkstyle repo in some directories on Windows #840
Description
Identified at #839 (comment) ,
When running diff.groovy with the checkstyle on my local, I got the following error:
Cloning into 'repositories\checkstyle'...

This shows I can't do this in a nested directory (M:\checkstyleWorkspaceEclipse\contribution\checkstyle-tester) of 61 characters.
I tested this and I can't clone checkstyle into a path of 71 characters or more.
\contribution\checkstyle-tester\repositories\checkstyle is 56 characters, which doesn't include the drive (2 characters), leaving me 13 characters to put the contribution directory somewhere if I choose.
We should allow users to override the repository directory. It creates issues and a lag to put it into the path of git even with the gitignore when I was working with this on linux.
