git-fetch--tool and contrib/examples/git-fetch.sh

When git-fetch was builtin-ized the previous script was moved to 
contrib/examples.  Now, it is the sole remaining user for most of 
git-parse-remote (except for get_remote_url) and for git-fetch--tool.

Would it make sense to remove git-fetch--tool, the dead parts of 
git-parse-remote, and contrib/examples/git-fetch.sh?  Anyway, the script 
is very involuted unlike the other scripts in contrib/examples.
