Title: Update the --debug support for osx

the backtrace format is tweaked a bit to include the function arguments too. The --debug option should now start FontForge for you, all you need to do is
bt
q

and the session is logged into /tmp/FontForge-Debug-Output.txt so that you can easily attach that file to a bug report.
