Summary: There are a few small bugs with the code that launches the editor from the packager:
* First of all, the filepath is not escaped which means tokens like `(` or spaces will mess up the process execution. Dropbox unfortunately decided to use spaces in its enterprise product, so I was getting this error:
* Next, the line number argument formatting was assumed to be in a specific format (`:%d`) which actually errors out vim and other editors.
* Lastly, the process was started synchronously but not attached to the stdin / stdout of the parent process. This means that only editors like mvim, sublime, and others would work since they spawn a new window. Editors like emacs, vi, nano, etc wouldn't work and instead just hang at the command line.
So I whipped up this diff to fix a number of these issues, demo here:
