[PATCH v3 0/2] git-jump: support Emacs

Add an optional argument 'stdout' to print the quickfix lines to standard output. It can be used with M-x grep on Emacs.

Detect emacsclient by GIT_EDITOR and invoke the function. Tested with EDITOR="emacsclient" and EDITOR="emacsclient -t".

  git-jump: add an optional argument '--stdout'
  git-jump: invoke emacs/emacsclient
