git remote set-url knew about the '--push' option to update just the pushurl, but it does not have a similar option for "update fetch URL and leave whatever was in place for the push URL".
This patch adds support for a '--fetch' option which implements that use case in a backwards compatible way: if neither --push nor --fetch are given, then the push URL is modified too if it was not set before. This is the case since the push URL is implicitly based on the fetch URL.
The documentation has also been updated and a missing '--push' option is added to the 'git remote -h' command.
Tests are also added to verify the documented behavior.

Hi,
Now and then I hit this issue where I want to change the remote where sources are fetched from without having to touch the push URL. Example:
git remote add gh git@github.com:Lekensteyn/git.git
# Avoid needing SSH for pulling from a repo, so change fetch URL
git remote set-url https://github.com/Lekensteyn/git.git
# Hmm, the fetch URL got changed too, let's fix that.
git remote add --push gh git@github.com:Lekensteyn/git.gitAfter this patch, I can use:
git remote add gh git@github.com:Lekensteyn/git.git
git remote set-url --fetch https://github.com/Lekensteyn/git.gitrather than being forced into a specific order:
git remote add gh https://github.com/Lekensteyn/git.git
git remote set-url --push gh git@github.com:Lekensteyn/git.gitThe functionality is implemented, but it might need a refactoring to reduce duplicate code. Translation strings also need to be updated (the current 'git remote set-url' strings are also not up to date).
