-Re: HBase shell split command acts incorrectly with hex split keys.

Try single quotes. The shell (ruby) may be trying to 'help you' by
interpreting your hex.
hbase(main):018:0> print "\x20\n"
hbase(main):019:0> print '\x20\n'
See how w/ double quotes it prints space and new line where when I
single-quote it, it prints out the literal?
At the end of the shell help it says:
"If you are using binary keys or values and need to enter them in the
double-quote'd hexadecimal representation. For example:
hbase> get 't1', "key\x03\x3f\xcd"
hbase> get 't1', "key\003\023\011"
hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40"
Looks like we need to add a line which says if you are using hex, to avoid
ruby's interpreting your intent, single-quote.
