Subject: [PATCH 1/5] pathspec: add new function to parse file
Date: Mon, 04 Nov 2019 19:26:41 +0000
Message-ID: <52e7a84a2ee61d6481286f6a32751107efc234d0.1572895605.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.445.git.1572895605.gitgitgadget@gmail.com>

From: Alexandr Miloslavskiy <alexandr.miloslavskiy@syntevo.com>

This will be used to support the new option '--pathspec-from-file' in
`git add`, `git-commit`, `git reset` etc.

Note also that we specifically handle CR/LF line endings to support
Windows better.

To simplify code, file is first parsed into `argv_array`. This allows
to avoid refactoring `parse_pathspec()`.

I considered adding `nul_term_line` to `flags` instead, but decided
that it doesn't fit there.

The new code is mostly taken from `cmd_update_index()` and
`split_mail_conv()`.
