[RFC/PATCH] Formatting variables in the documentation

[Tom Russello <tom.russello@grenoble-inp.org>]

Put each environment variable in the same format for more consistency.
Currently, in Documentation/git-config.txt GIT_CONFIG (l.138) has no
particular style whereas in Documentation/config.txt GIT_PROXY_COMMAND
has italic style ('GIT_PROXY_COMMAND' - l.437) and GIT_EDITOR is
monospaced (`GIT_EDITOR` - l.657)

As a first step, this patch changes GIT_* variables that where in
italic style to monospace font. It was obtained with

	perl -pi -e "s/\'(GIT_.*?)\'/\`\1\`/g" *.txt

Hello,

There is no agreement on this topic (the CodingGuidelines does not
mention it), it would be better if everyone follows the same rule: put
each environment variable in monospace style and write this rule in
the guide.

It is a good thing to have a consistent documentation however it
will be painful to change with a simple regex all occurences
(especially environment variables without any format) because some of
them are in paths or code section.

What do you think ?
