- fix incorrect parsing of whitespace in command.c (thanks to Magnus Lundin)

- fix infinite recursion in target_init_handler (thanks to jw and Magnus Lundin)
- fix CFI flash handlign with buswidth < 32bit (thanks to Daniele Orio for reporting this)
- add support for reading JTAG device id (currently only as debug output on startup)
