Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

# Create a test repo to pull into
git init test
cd $_
git remote add origin wrong-url
# Create a test repo to pull from
git init ../test2
cd $_
touch a
git add .
git commit -m 'commit to pull'
# Attempt to pull, setting remote.origin.url
# The following git commands will fail:
cd ../test
git -c remote.origin.url=../test2 pull
git -c remote.origin.url=../test2 fetch
# However, this succeeds:
git pull ../test2

What did you expect to happen? (Expected behavior)

The '-c' option should allow me to override the remote URL,
which, as a result of running `git remote add`, is configured as
follows in test/.git/config:

[remote "origin"]
	url = wrong-url

From git(1): 

-c <name>=<value>
    Pass a configuration parameter to the command. The
    value given will override values from configuration
    files.

What happened instead? (Actual behavior)

The following errors are produced for both 'fetch' and 'pull'
operations:

fatal: 'wrong-url' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Regardless of the -c option, the commands above use the url
'wrong-url' from .git/config.

What's different between what you expected and what actually
happened?

The -c option is not respected.

Anything else you want to add:

It may be that this is not supported, but if that's the case, I
missed any documentation saying so.
