Passing arbitrary arguments to functions through "emacsclient --eval" sometimes requires complicated escaping to avoid them being parsed as Lisp (as seen in emacsclient-mail.desktop before this change). The new variable 'server-eval-args-left' allows access to the arguments before they are parsed as Lisp. By removing arguments from the variable before they're parsed, a snippet of Lisp can consume arguments, as in emacsclient-mail.desktop. org-protocol might be able to use this as well, which might allow it to drop its current advice on server-visit-files. * etc/emacsclient-mail.desktop: Use 'server-eval-args-left'. * lisp/server.el (server-eval-args-left): New variable. (server-process-filter, server-execute): Make '-eval' arguments available through 'server-eval-args-left'. * lisp/startup.el (argv): Mention 'server-eval-args-left' in docstring. * etc/NEWS: Announce 'server-eval-args-left'. * doc/emacs/misc.texi (emacsclient Options): Document 'server-eval-args-left'.
