c17577318d Applied patch from David MacMahon <davidm -at- astro -dot- berkeley -dot- edu>. 
Adds physical units support to comedilib demo programs.
I changed one of the format strings to help line up values better in the
'cmd' example.

761ffc3e90 Applied (slightly modified) patch from David MacMahon 
<davidm -at- astro -dot- berkeley -dot- edu>.
Reports specific error string (strerror(errno)) if comedi_open fails (I
changed the format slightly from David's).
Displays subdevice flags as a hexadecimal number.

998c091e1e doing a retry for the preload write is useless, since the command 
hasn't started yet.  Print a useful error message and exit instead.
