[RFC] Case insensitive URL rewrite

Hi,

the "url.<someURL>.insteadOf" git config is case sensitive. I understand that this makes sense on case sensitive file systems. However, URLs are mostly case insensitive:

Consider this: git clone https://GIThub.com/GIT/GIT git clone https://github.com/git/git

Both commands will clone the same repository.

Interestingly enough this works, too: git clone git@GIThub.com:GIT/GIT

What do you think about a flag that makes these rewrites case insensitive? E.g. with the following config flag:

[url "<actual url base>"]
	insteadOf = <other url base>
	ignorecase = true

Thanks, Lars
