[PATCH v1] Documentation: git-rev-parse: clarify that --git-dir does not necessarily show relative paths

[Jon Seymour <jon.seymour@gmail.com>]

The previous documentation was misleading because it lead the reader to believe
that --git-dir would always show a relative path when, in fact, the actual
behaviour does not guarantee this.

Rather, it was intended that the advice be given that if a relative path
is shown, then the path is relative to the current working directory and not some
other directory (for example, the root of the working tree).
