Summary:                    applets/usage_compressed cannot parse od(1) output
on Mac OS X (fix attached)
Description: 
On Mac OS X (10.4.8) (and presumably other BSD systems) the output of od(1)
differs from Linux.

Mac:
echo foo | od -v -t x1 
0000000    66  6f  6f  0a                                                
Linux:
0000000 66 6f 6f 0a

The multiple spaces result in sed producing a bogus C file that gives
compile errors.

static const char packed_usage[] =
"\x  \x42\x 5a\x 68\x 31\x 31\x 41\x 59\x 26\x 53\x 59\x 9b\x ea\x 54\x
c8\x 00\x 00"

A trivial patch to ignore extra spaces:
