If you set the command to save before, it will think the file is up- 
to-date (even though the command makes a second save), and if you set  
the output to discard, you should get rid of the latter problem (then  
also remove the » && cat "$TM_FILEPATH"«).

It does however not handle the case where the file is untitled.






Just FYI (meant for the list) I am currently (amongst other) looking  
into extending commands to be used in various (callback) events, and  
directly on files (from the file browser). So long-term the way to  
strip trailing spaces (and similar) will be a method very similar to  
this (but with a slightly extended infrastructure to make it more  
graceful).
