[PATCH 1/9] git-rev-parse.txt: clarify --git-dir

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

From: Jonathan Nieder <jrnieder@gmail.com>

The current behavior is often to print an absolute path rather than
a ../../etc string, but callers must be ready to accept a relative
path, too. The most common output is ".git" (from the toplevel of
an ordinary work tree).

 OK. Take 2. I think it is bisectable this time. This replaces
 35-42 (the fixing part, no need to resend 34 unchanged patches). More notes
 on each patch.
