I agree that the LF after the macro could be skipped. But 2 LFs in place
before I find useful, to start on a clean line. 73 Fred from

* src/write_keyer.c: shorten macro output in digimode
- old implementation had 5 empty lines for each macro output
(1 from message eol, 2 from write_keyer routine, 1 from echo,
1 from fldigi)
- dropped 1 of the lines in output string
- used '-n' switch to force echo to not append a further newline
- simplify command formatting
