From: Alexandr Miloslavskiy <alexandr.miloslavskiy@xxxxxxxxxxx> 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()`.
