This adds dumping for the tune= field that was just added in commit
276118107, but also:
* Instrument name gets put in a comment at the end of line - like the
current configuration in config.py.
* Instrument calls get split across two lines when there are many
parameters, to try to keep to 80 columns.
* off1= and off2= parameters now get outputted as +x or -x rather than
just x or -x.
