Subject: add: support the --pathspec-from-file option

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