This prepares 'git-difftool' and its documentation for
mainstream use.
'git-difftool-helper' became 'git-difftool--helper'
since users should not use it directly.
'git-difftool' was added to the list of commands as
an ancillaryinterrogator.

This is another consistency cleanup to make git-difftool's options
match git-mergetool.

I don't even know what $COMSPEC means so let's be safe and use the
same perly $^O test add--interactive uses. While we're at it, make
git-difftool match the prevalent git-perl style.

Some users have different mergetool and difftool settings, so teach
difftool to read config vars from the difftool.* namespace. This allows
having distinct configurations for the diff and merge scenarios.
We don't want to force existing users to set new values for no reason
so difftool falls back to existing mergetool config variables when the
difftool equivalents are not defined.

This patch makes the difftool docs always refer to the
git-difftool script using the dashed form of the name.
Only command examples use the non-dashed form now.

'git difftool' is a git command that allows you to compare and edit files
between revisions using common merge tools. 'git difftool' does what
'git mergetool' does but its use is for non-merge situations such as
when preparing commits or comparing changes against the index.
It uses the same configuration variables as 'git mergetool' and
provides the same command-line interface as 'git diff'.
