Subject: [PATCH v4 6/7] t3701-add-interactive: test add_i_show_help()

From: "Slavica Djukic via GitGitGadget" <[email-masked]>
Date: Fri, 25 Jan 2019 04:23:35 -0800 (PST)

From: Slavica Djukic <[email-masked]>

Add test to t3701-add-interactive to verify that add_i_show_help()
outputs expected content.
Also, add it before changing git-add--interactive.perl's help_cmd
to demonstrate that there are no changes introduced by the
conversion to C.

Prefix git add -i call with GIT_PAGER_IN_USE=true TERM=vt100
to force colored output on Windows.
