[PATCH v2 1/4] completion: squelch stray errors in sparse-checkout completion

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

If, in the root of a project, one types

    git sparse-checkout set --cone ../<TAB>

then an error message of the form

    fatal: ../: '../' is outside repository at '/home/newren/floss/git'

is written to stderr, which munges the users view of their own command.
Squelch such messages by using the __git() wrapper, designed for this
purpose; see commit e15098a314 (completion: consolidate silencing errors
from git commands, 2017-02-03) for more on the wrapper.
