Subject: [PATCH] Don't save to existing location if not modified

Holding down cmd-S too long will cause multiple synchronous saves which can be expensive if there is heavyweight linter activity listening for the save events.

This simply debounces it (in a sense) by not saving it the file if it is known not to have changed. Also this has no effect on saving new files for the first time.
