Subject: [PATCH 2/7] submodule foreach: correct path computation in recursive submodules
Date: Mon, 28 Mar 2016 16:28:18 -0700	[thread overview]
Message-ID: <1459207703-1635-3-git-send-email-sbeller@google.com> (raw)
In-Reply-To: <1459207703-1635-1-git-send-email-sbeller@google.com>

The test which is fixed by this patch would report
    Entering 'nested1/nested2/../nested3'
instead of the expected
    Entering '../nested1/nested2/nested3'

because the prefix is put unconditionally in front and after that a
computed display path with is affected by `wt_prefix`. This is wrong as
any relative path computation would need to be at the front. By emptying
the `wt_prefix` in recursive submodules and adding the information of any
relative path into the `prefix` this is fixed.
