commit: support the --pathspec-from-file option

Decisions taken for simplicity:
1) For now, `--pathspec-from-file` is declared incompatible with
   `--interactive/--patch`, even when <file> is not `stdin`. Such use
   case it not really expected. Also, it would require changes to
   `interactive_add()`.
2) It is not allowed to pass pathspec in both args and file.

--pathspec-from-file=<file>::
Pathspec is passed in `<file>` instead of commandline args. If
`<file>` is exactly `-` then standard input is used. Pathspec
elements are separated by LF or CR/LF. Pathspec elements can be
quoted as explained for the configuration variable `core.quotePath`
(see linkgit:git-config[1]). See also `--pathspec-file-nul` and
global `--literal-pathspecs`.
--pathspec-file-nul::
Only meaningful with `--pathspec-from-file`. Pathspec elements are
separated with NUL character and all other characters are taken
literally (including newlines and quotes).
-u[<mode>]::
--untracked-files[=<mode>]::
Show untracked files.
