Subject: [PATCH 2/9] submodule--helper: prefer strip_suffix() to ends_with()
Date: Mon, 12 Nov 2018 09:47:04 -0500	[thread overview]
Message-ID: <20181112144703.GB7400@sigill.intra.peff.net> (raw)
In-Reply-To: <20181112144627.GA2478@sigill.intra.peff.net>

Using strip_suffix() lets us avoid repeating ourselves. It also makes
the handling of "/" a bit less subtle (we strip one less character than
we matched in order to leave it in place, but we can just as easily
include the "/" when we add more path components).
