Feature request - show result of URL rewrites

Hello

Hopefully this is the right place to submit feature requests - let me know if there's somewhere else I should use!

Git lets you rewrite URLs using "url.<base>.insteadOf"

Can you add a git-config option to show the result of this rewriting whenever this occurs, as debugging more complicated rules can be difficult/wasn't obvious without Wireshark.

E.g. you could have the option 'url.printRewrites [True/False]' which would print the line "Rewrote url 'git://github.com/git/git' to 'https://github.com/git/git'" to terminal/stdout  when set to True.

Thanks
