  To me this is the even more important reason.  Some registry strings do
include the trailing zero, some don't; cygwin shouldn't tamper with it.  And
it would seem _very_ wrong to me if by querying a value, and then using the
result returned to re-set the value, the value should change in length.

  And since the patch unconditionally chops one off the size without
verifying whether or not the nul terminator is actually present, it would do
the wrong thing for some strings.
