[RFC/PATCH 2/2] Doc: State the exact git version string

[Philip Oakley <philipoakley@iee.org>]

Provide the regular expression that matches the
'git --version' strings.

Scripts in the wild, including 'git gui', check the git version.

Should the string be described by a regular expression?

How to format the regular expression for asciidocs - it doesn't
get made correctly - I'm not sure what special magic incantation
is needed here.
