>Description:
If in ddb the 'x' command with modifiers 'b','h','l','L' dont print anything:

db{0}> x/b c9d47a40,64
0xc9d47a40:

db{0}> x/h c9d47a40,64
0xc9d47a40:

db{0}> x/l c9d47a40,64
0xc9d47a40:

db{0}> x/L c9d47a40,64
0xc9d47a40:

and 

db{0}> x/m c9d47a40,8
0xc9d47a40:     282a9ac0 e41594c0 6c2a9ac0 a80d94c0     (*......l*......
0xc9d47a50:     30229ac0 dc1d94c0 64329ac0 901494c0     0"......d2......

prints *bigendian* values on this i386; quite confusing. If its memory bytes
it should print it should space between the two digits for otherwise it can be
misread.


>How-To-Repeat:
Enter ddb and try to print out some memory with the 'x' command.

        
>Fix:
In db_examine() (sys/ddb/db_examine.c) the 'b','h','l','L' cores are only
setting up variables but dont print a thing whereas 'o' or 'u' work fine.
