I think with this change all editors can benefit. The format "git jump" is producing is something easily consumed. I think consumption of output from tools is far more common in editors than communication between multiple instances. As an aside the fact that as is "git jump" invokes "$GIT_EDITOR" with the "-q" option makes an implicit assumption the editor will be Vim or something very much like it. To be very clear I don't mean to say this means only Vim should be considered. However it's also making the implicit assumption that passing the "-q" option is valid for any "$GIT_EDITOR" and does not cause an error like that seen when trying to override "$GIT_EDITOR" with cat. This change means other editors can invoke "git jump" without fear of such a situation, increasing usability. Arguably the most interoperable way for "git jump" to work would be to output the formatted lines and do nothing else, leaving it to users to choose how to operate upon the output/invoke editors. Of course such a change would break the workflow of anyone who uses "git jump" today and isn't a valid option.
