From: Alexandr Miloslavskiy <alexandr.miloslavskiy@xxxxxxxxxxx>
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.

the last commit without committing changes that have
already been staged. If used together with `--allow-empty`
paths are also not required, and an empty commit will be created.
+
+--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 are not expected to be quoted.
