Subject: [PATCH 2/2] built-in add -i: accept open-ended ranges again
Date: Thu, 16 Jan 2020 08:33:07 +0000
Message-ID: <7e4bf4bbbcd8c81a19d690aee379042e47246947.1579163587.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.528.git.1579163587.gitgitgadget@gmail.com>

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The interactive `add` command allows selecting multiple files for some
of its sub-commands, via unique prefixes, indices or index ranges.

When re-implementing `git add -i` in C, we even added a code comment
talking about ranges with a missing end index, such as `2-`, but the
code did not actually accept those, as pointed out in
https://github.com/git-for-windows/git/issues/2466#issuecomment-574142760.

Let's fix this, and add a test case to verify that this stays fixed
forever.
