Re: [PATCH] git: update documentation for --git-dir

"Heba Waly via GitGitGadget" [off-list ref] writes:

For example, if the user runs `git --git-dir=<path> status`, git
will not be able to figure out the work tree path on its own 

It is not "not be able to figure out".  Specifying GIT_DIR (either
with environment or the --git-dir option) tells Git that the $cwd is
the top of the working tree unless otherwise specified (e.g. with
GIT_WORK_TREE environment).  If you have to say something, saying
"When GIT_DIR is specified, the usual repository discovery is
skipped and the current directory is taken as the top level of the
working tree unless otherwise speciffied" is probably OK.
