Subject: [PATCH 04/11] git: ->qx: respect caller's $/ in array context
Date: Tue,  9 Feb 2021 07:09:30 -0100
Message-ID: <20210209080937.4678-5-e@80x24.org> (raw)
In-Reply-To: <20210209080937.4678-1-e@80x24.org>

This could lead to bad results when doing ls-tree -z
for v2 import in case there's multiple files.  In any case,
the `local $/ = "\0"' in Import.pm is also eliminated to
reduce potential confusion and surprises.
