mvim: '+' argument doesn't work with '--remote' and friends

Steps to reproduce

1. Open a terminal.
2. Type

   mvim + --remote <filename>
   

   or

   mvim +2 --remote <filename>
   

, where <filename> is an existing file with more than one line.
4. Observe that the cursor is at the top of the file, not the end as directed by + (nor the line specified by +n).

Expected behaviour

Per mvim --help:

+ Start at end of file
+<lnum> Start at line

Upon opening, the cursor should have been positioned on the last line of the file (or the line directed by the +<lnum> form).

Vim configuration where issue is reproducable

https://gist.github.com/tomory/65de091000d9f89732f33be98d39848e

Issue has been tested with given configuration

• by running MacVim.app from GUI macOS interface
• by running vim/gvim/etc installed by MacVim
• by running other versions of vim (e.g. /usr/bin/vim)

Issue has been tested with no configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution)
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)

Other conditions

• The both Homebrew packages "vim" and "macvim" are installed

Reproduziere das Verhalten mit mvim --clean unter Verwendung von +, +2 und --remote wie beschrieben, und verfolge anschließend die mvim-Befehlszeilenverarbeitung für diese Argumente. Als erledigt gilt die Aufgabe, wenn der Cursor bei + am Ende der Datei und bei +n in der angeforderten Zeile geöffnet wird, auch wenn --remote verwendet wird.
