reset: support the `--pathspec-from-file` option
Decisions taken for simplicity: 1) For now, `--pathspec-from-file` is declared incompatible with `--patch`, even when <file> is not `stdin`. Such use case it not really expected. Also, it is harder to support in `git commit`, so I decided to make it incompatible in all places. 2) It is not allowed to pass pathspec in both args and file.

DESCRIPTION

-----------
|

In the first and second form, copy entries from `<tree-ish>` to the index.

||||
In the third form, set the current branch head (`HEAD`) to `<commit>`,
|
||||
In the first three forms, copy entries from `<tree-ish>` to the index.
|
||||
In the last form, set the current branch head (`HEAD`) to `<commit>`,
|
||||
optionally modifying index and working tree to match.
|
||||
The `<tree-ish>`/`<commit>` defaults to `HEAD` in all forms.
|
||||
|
||||
'git reset' [-q] [<tree-ish>] [--] <pathspec>...::
|
||||
This form resets the index entries for all paths that match the

'git reset' [-q] [--pathspec-from-file=<file> [--pathspec-file-nul]] [<tree-ish>]::
|
||||
These forms reset the index entries for all paths that match the
|
||||
`<pathspec>` to their state at `<tree-ish>`. (It does not affect
|
||||
the working tree or the current branch.)

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
