Bug: Git checkout case Insensitive branch name compare

Bugs Details:

Git checkout case Insensitive branch name compare

Steps to Reproduce:

 I have a remote branch which is as shown below.
Example: feature_12345_write.netCodeForSomeFeature

 I used the git command on git bash and typed
"feature_12345_write.NetCodeForSomeFeature" thinking I am mapping
"feature_12345_write.netCodeForSomeFeature" locally.

So after I got the branch locally, I tried git pull and I see the following "Your configuration specifies to merge with the ref 'refs/heads/feature_12345_write.NetCodeForSomeFeature' from the remote, but no such ref was fetched.

 Although when I did "git log", it shows proper history for
"feature_12345_write.netCodeForSomeFeature" branch.

However when I use the command "git pull --rebase origin branch" it says "fatal: Couldn't find remote ref feature_12345_write.NetCodeForSomeFeature" Because the remote branch has 'n' instead of 'N' in '.net' for branch name.

This is because I used "git checkout branch" instead of "git checkout branch origin/remote branch name" since the local branch name I wanted was the same as the remote branch name.

I don't see this in other branches.

I think the command is not considering case sensitivity of characters in the branch name.

Thanks.
