Document GIT_SSH environment variable alongside other variables

Browse source 
The GIT_SSH environment variable has survived for quite a while
without being documented, but has been mentioned on list and on
my day-job repositories can only be accessed via magic supplied
through the wonderous hack that is GIT_SSH.

Advertising it alongside other "low level magic" such as GIT_PAGER
and GIT_MERGE_VERBOSITY will certainly help others who need to
spread their own pixie dust to make things work.

the 'username@host' (or just 'host') from the URL and the
shell command to execute on that remote system.

To pass options to the program that you want to list in GIT_SSH
you will need to wrap the program and options into a shell script,
then set GIT_SSH to refer to the shell script.

Usually it is easier to configure any desired options through your
personal `.ssh/config` file. Please consult your ssh documentation
for further details.
'GIT_FLUSH'::
If this environment variable is set to "1", then commands such
as git-blame (in incremental mode), git-rev-list, git-log,
