Patch is different for branch.   Problem is made worse by the makeColumnName ruby method.

> Binary values in the shell don't seem to be formatted correctly.  For example:
> {code}
> hbase(main):007:0> put 't1', 'r1', 'f1:q1', "\x91", 1000
> 0 row(s) in 0.0160 seconds
> hbase(main):008:0> scan 't1'
> ROW                          COLUMN+CELL
>  r1                          column=f1:q1, timestamp=1260417826655, value=\357\277\275
> 1 row(s) in 0.1090 seconds
> {code}
> In this case we insert a single byte (double quotes needed for it to interpret the hex
value correctly), but when formatted, it appears as 3 bytes in octal.
> The same thing happens when the data is inserted via the Java api.  For example, this
code:
> {code}
> HTableDescriptor tableDesc = new HTableDescriptor("t2");
> tableDesc.addFamily(new HColumnDescriptor("f1"));
> HBaseAdmin admin = new HBaseAdmin(new HBaseConfiguration());
> admin.createTable(tableDesc);
> HTable table = new HTable("t2");
> Put put = new Put(Bytes.toBytes("r1"));
> put.add(Bytes.toBytes("f1"), Bytes.toBytes("q1"), new byte[] {(byte) 0x91});
> table.put(put);
> Result result = table.get(new Get(Bytes.toBytes("r1")));
> System.out.println(Bytes.toStringBinary(result.raw()[0].getValue()));
> {code}
> Prints out {{\x91}}
> And then accessing via shell gives:
> {code}
> hbase(main):009:0> scan 't2'
> ROW                          COLUMN+CELL
>  r1                          column=f1:q1, timestamp=1260418531959, value=\357\277\275
> 1 row(s) in 0.1100 seconds
> {code}
