\b character escapes in CLI usage

Hi all,

I'm not sure if this is a bug, but it definitely feels like a bug.

A colleague of mine was going through the documentation for the git configuration file format and noticed that \b is a permitted escape.

In some places, such as trying to fetch a remote with this in the URL, git will render the character differently.

[remote "backslashb"]
        url = "\b"
        fetch = +refs/heads/*:refs/remotes/backslashb/*

$ git fetch backslashb fatal: '?' does not appear to be a git repository fatal: Could not read from remote repository.

When using "git config --list" however, this is emitted in its raw format, and can be used to mask or hide an actual (probably invalid) value:

$ cat .git/config
[core]
        somevalue = "true\b\b\b\bfalse"
$ git config --local --list
core.somevalue=false

Should "git config" be smarter here and print something other than a literal backspace to the terminal, like "git fetch" does?
