Relative paths and $ENVVARS would need explanation; not sure what
needs to be said about ~user since the new behavior is what people
expect to just work.  Would it go in git-config.txt if something
were added?

Traditionally, we never has interpret ~/ or ~user/.  Users expected that
they need to spell it like:

        [core]
                excludesfile = "/home/joe/.my-ignore-pattern"

Especially since this is called "variables", it is natural, without
explanation, to expect this not to work, just like this use of a variable
won't work:

        $ EDITOR='~/bin/editor' ;# notice the single quote
        $ export EDITOR;
        $ git commit -a
        fatal: exec ~/bin/editor failed.

Your patch improves the situation and now allow:

        [core]
                excludesfile = "~/.my-ignore-pattern" 

If you do not document that it is now possible for this particular
configuration variable, the users will never know.
