v1.2.9

Improvements to its behavior on FreeBSD, recognizing the extensions .pico and .nossppico and treating them
as the object files they are. Improvements to the dependency command line switches, so they do not get confused as inputs. Use of the debug/elf and debug/macho packages to recognize file types, and use this capability to have a fallback when simple minded (but fast) pattern matching doesn't work.
