[RFC] Subtle differences in passing configs to git clone

Hi,

I stumbled across the following today:

(1) git -c foo.bar="foobar" clone <URL>

--> uses the config temporarily

(2) git clone -c foo.bar="foobar" <URL>

--> uses the config and writes it to .git/config

This was introduced in 84054f7 ("clone: accept config options on the command line") and it makes total sense. However, I think this subtitle difference can easily confuse users.

I think we should tell the users that we've written to .git/config. Maybe something like this:

git clone -c foo.bar="foobar" <URL> Cloning into 'test'... Writing foo.bar="foobar" to local config... remote: Counting objects: 2152, done. remote: Compressing objects: 100% (33/33), done. remote: Total 2152 (delta 19), reused 0 (delta 0), pack-reused 2119 Receiving objects: 100% (2152/2152), 328.66 KiB | 217.00 KiB/s, done. Resolving deltas: 100% (1289/1289), done.

What do you think?

Thanks, Lars
