This patch adds whitespace to the printed hex numbers to have an aligned ASCII printout at the end of the line. This changes for example the md output from: ---8<--- OMAP3 Tricorder # md.l $loadaddr 5 82000000: 30200109 20a4028c 90010000 08a00000 .. 0... ........ 82000010: 01010000 .... --->8--- to ---8<--- OMAP3 Tricorder # md.l $loadaddr 5 82000000: 30200109 20a4028c 90010000 08a00000 .. 0... ........ 82000010: 01010000 .... --->8--- The cost of this is about 72 byte .text increase (tested with at91 build).
