Is it possible to configure git to, by default, when using git fetch, fetch only the current branch and master from the remote, without explicitly mentioning the current branch name?

I know that I can achieve this exact fetch with this command:

git fetch origin $(git rev-parse --abbrev-ref HEAD) master:master

But I would like to have the same behavior when I run only

git fetch

Is that possible to configure? For instance, by some magic refspec in the .git/config file.

Note that, in the configuration, I don't want to hard code the name of the current branch, and I don't want to use aliases.
