Open Files with Terminal Vim by default [mac, iterm]

gistfile1.txt

If you want your terminal vim to open files you double click, follow the following steps (MacOS only):
 
1. Open Automator
2. Select Application
3. Copy the attached file
4. Save and set as default for opening files

Multiple files are opened in vim tabs.
If there is already a vim instance running, files are opened in it.

Bugs / Problems:
- does not open files when vim instance is in insert mode
- vim instances running e.g. in tmux are not recognized

	end if
end run

for iterm2 on latest os x things change a little. Here's what I use. It's not 100% the same, but it suits my needs.

But this is only for iTerm, what about the regular zsh terminal?
