Hmm, don't we have xmemdupz() for this?

No // comments please.

At least use xmalloc(); also isn't sizeof(char) by definition 1?

It may be just a style thing, but I'd rather see this caller call
color_parse() first, and after letting that function validate the end-user
input, call string_list_insert().

Also what happens when there are two entries that talk about the same
remote branch in the configuration? Such a configuration is not an error;
your ~/.gitconfig may say one thing for remote.origin.master and your
repository specific .git/config may override it for a particular
repository.

Who said a remote name is terminated with (and cannot contain) a slash?

Shouldn't this code be consulting the configuration file to learn the
remote mapping, e.g.

    [remote "frotz"]
        fetch = +refs/heads/*:refs/remotes/nitfol/*

so that remote branches from "frotz" remote, that happen to be stored
under refs/remotes/nitfol/ hierarchy, are painted in the correct color?
