stack commented on HBASE-859:
-----------------------------

Text had same problem as binary keys. If keys were URLs and URL included any of 
below characters, then we had same problem:

> HBASE-832 had to make an ugly hack to address fact that rows that included 
> the delimiter -- or a byte < delimiter -- messed up sorting in .META.  Fix 
> the ugly hack, and while we're at it, add a byte for flags to the HSK so can 
> mark if key is a meta key, a delete key (cell/family/row), etc.
