Subject: [PATCH 22/37] solver: restore diagnostics and deal with CRLF
Date: Mon, 21 Jan 2019 20:52:38 +0000	[thread overview]
Message-ID: <20190121205253.10455-23-e@80x24.org> (raw)
In-Reply-To: <20190121205253.10455-1-e@80x24.org>

Apparently Email::MIME returns quoted-printable text
with CRLF.  So use --ignore-whitespace with git-apply(1)
and ensure we don't capture '\r' in pathnames from
those emails.

And restore "$@" dumping when we die while solving.
