Bram Schoenmakers noticed that git-config document was formatted
incorrectly. Depending on the version of AsciiDoc and docbook
toolchain, it is sometimes taken as a numbered example by AsciiDoc,
some other times passed intact to roff format to confuse "man".
Since we refer to the repository metadata directory as $GIT_DIR
elsewhere, work it around by using that symbolic name.

If not set explicitly with '--file', there are three files where
git-config will search for configuration options:
-.git/config::
+$GIT_DIR/config::
Repository specific configuration file. (The filename is
of course relative to the repository root, not the working
directory.)
